The 24-year-old man was detained this morning at an address in east London on suspicion of assisting an offender.

He’s been bailed to a date in late April.

The man is not a member of staff at Wandsworth Prison.

The arrest, carried out by officers from the Met’s Counter Terrorism Command as part of their ongoing investigation, is linked to the alleged escape of 22-year-old Daniel Khalife from HMP Wandsworth in September.

Khalife is due to go on trial at the Old Bailey in October after pleading not guilty to charges alleging he escaped from HMP Wandsworth. He will also face trial in relation to three other charges.

Detective Chief Superintendent Gareth Rees, of the Met’s Counter Terrorism Command, said:

“This arrest follows months of careful investigation into the alleged escape and enquiries remain ongoing into this.

“We understand that there will be significant public and media interest in this arrest but with Khalife now charged and awaiting trial, it is extremely important that people do not report, comment or share information – including online – which could in any way prejudice these future court proceedings.”
