A migrant sex offender mistakenly released from an Essex prison was last seen in north London on Friday evening, according to the Metropolitan Police.

Hadush Kebatu was spotted shortly before 20:00 on Friday in the Dalston area of Hackney, the Met Police said in a statement.

CCTV footage also shows him at a library in Dalston Square at around 18:00, wearing a prison-issue grey tracksuit and carrying a white bag decorated with pictures of avocados.

Additional officers have been deployed to the area to locate the Ethiopian national, who was set free from HMP Chelmsford four weeks after being jailed for sexually assaulting a 14-year-old girl and a woman in Epping, Essex, while staying at the Bell Hotel as an asylum seeker.

Appealing to Kebatu, Cmd James Conway said: "We want to locate you in a safe and controlled way."
