Piet Hoffmann’s three-year infiltration of Wojtek

Piet Hoffmann’s three-year infiltration of Wojtek is a long operation built on a criminal identity credible enough to pass scrutiny and dangerous enough to reach the organization’s leadership. Its success gives the police access to intelligence they could not otherwise obtain, but the same covert methods that make the infiltration possible also leave Hoffmann exposed and help conceal crimes from the official record.

Building Paula

The operation began after the national crime operations division identified Wojtek Security International as a flourishing branch of Eastern European organized crime, already established in Norway and Denmark. A controller at City Police sent Erik Wilson the intelligence report and emphasized the qualities that could make Hoffmann convincing as Paula: Polish was his other mother tongue, his profile appeared in the ASPEN criminal-intelligence database, and his criminal record could withstand checks. A prepared identity was not simply a cover story; it had to hold up against institutional records and the organization’s own scrutiny.

Three years of constructing that role brought Paula to the top of Wojtek. Hoffmann communicated directly with the deputy CEO and the Roof in Warsaw, behind the facade of a Polish security firm. Wilson judged the resulting intelligence to be worth the work of forty detectives: Paula knew more about the organization than the Swedish police did. The operation’s duration measures both its reach and its danger. Wilson accepted the exposure and continuing threat because this access made the work seem worthwhile.

From access to prison

The transition into Aspsås prison took Hoffmann from a role he had spent years constructing into a real, highly controlled institution. Although he had mapped the buildings from the church tower, studied the bars on the windows, and learned about Block G’s prisoners and staff with Wilson’s help while on remand, he had never crossed the prison walls. His first entry came under escort, in leg irons, through the security registration entrance rather than the ordinary visitors’ door. The advance preparation could not make the place familiar: it had given him a plan, not experience of living inside it.

After ten days, the routine had become starkly restrictive. For twenty-three hours a day he remained in a small cell behind a metal door, without visitors, newspapers, television, or radio. Later, a principal officer showed him the unit’s practical rules, including where to go and the precise lock-in time. With the unit empty for several hours, Hoffmann had time to absorb the fact that this was now his home. The operation’s move into prison thus altered more than his location: it placed his survival inside a closed system of schedules, access, and isolation.

Establishing a prison identity

Hoffmann prepared his arrival in the unit as deliberately as he had prepared Paula. He had seen photographs of its fifteen other prisoners and knew their backgrounds. Before they returned, he sat in the television corner, where each would see him enter the social field of the unit. He chose not to wait hidden in his cell or seek permission to occupy the common space: he sat in another prisoner’s favored chair, took marked cards, and began a game of solitaire. These were calculated public gestures, meant to establish that he would not present himself as frightened or deferential.

He was looking for Stefan Lygas and Karol Tomasz Penderecki, two Wojtek members serving long sentences at Aspsås. They were allies in his effort to remove competitors and take control of the prison drug market, but also potential executioners if his identity as Paula were exposed. Their position therefore made the prison both the operation’s next arena and its sharpest point of vulnerability. They had prepared the other prisoners for Hoffmann’s arrival, circulating information about his alleged crimes, associates, and standing with Eastern European criminal groups. Copies of police and prison records, along with his latest judgment, supplied documentary support for the identity he needed the unit to accept.

At supper, two older prisoners demanded to see his papers. Stefan and Karol Tomasz moved to intervene, but Hoffmann let the questions proceed. He understood that respect in this setting depended partly on shared hostility toward sexual offenders, and he answered the challenge by objecting to the men sitting too close rather than retreating from scrutiny. The scene shows how the operation’s manufactured credentials had to be sustained through conduct as well as documents: prison status was tested in person, in front of the people whose cooperation he needed.

Institutional time and concealed records

The operation’s consequences extend beyond Hoffmann’s own three years. When his cover was at risk inside Block G, ten members of the prison riot squad entered in protective equipment; six remained to deter further violence while four escorted him to the voluntary-isolation unit in Block C. Isolation offered distance from prisoners in other units, but it also made his continued safety depend on the institution’s decisions about where he could be held. The transfer was a response to exposure, not an escape from the threat that exposure created.

The later investigation reveals a second chronology running alongside official casework. Ewert Grens found 302 secret intelligence reports from the previous year describing informant work that uncovered one crime while giving rise to another. Some concerned investigations that had failed despite relevant knowledge already being held within the police. Grens told prosecutor Lars Ågestam that the three cases under discussion were only three of the 302, and that Ågestam had been involved in twenty-three unsuccessful prosecutions without access to the fuller secret reports. The separation between covert intelligence and official investigation therefore had consequences for cases beyond Hoffmann’s own operation.

The book’s factual coda places this practice on a broader institutional timescale: the Swedish Police Service has used criminals as covert human intelligence sources, while denying and concealing that cooperation. It states that criminal records and intelligence databases have been used to build credible backgrounds, with extensive alteration becoming routine, and that exposed informants may be disavowed while the organizations they infiltrated are left to respond. In that light, the three-year infiltration is not only a measure of Hoffmann’s endurance or access. It is also an example of how a successful covert identity can depend on manipulated records and secrecy that carry costs into the justice system.
