Mr Justice Hayden said at a hearing on Monday that, following his release, Adeyeye “strolled about” the London area and “had a very nice dinner” and “quite a lot of drink” at a local pub, before transferring thousands of pounds to others from a bank account.
It is believed Adeyeye may have travelled to Spain the following day, all before prison staff contacted the Metropolitan Police on the afternoon of 24 April.
Mr Justice Hayden said: “The public is entitled to expect far better than this.”
Last June, the same judge ruled that Adeyeye, a dual British-Nigerian national, abducted Laurys from his mother, Claire N’Djosse, in France and took him to the African country via the UK.
The news of Adeyeye’s release comes after a former asylum seeker who sexually assaulted a 14-year-old girl was mistakenly freed from HMP Chelmsford in October.
The manhunt for Hadush Kebatu cost police forces more than £150,000, a review found.
Data published by the Ministry of Justice (MoJ) last month showed that 179 inmates were wrongly released between April 2025 and March 2026.
The MoJ said it was working with police to recapture Adeyeye, and was investing up to £82m to drive down accidental releases, adding: “We inherited a prison system in crisis after years of underinvestment, which has resulted in unacceptable rises in release in errors.”
