A manhunt for Khalife was launched after he escaped from HMP Wandsworth on September 6.

"The investigation to locate and arrest Khalife involved over 150 officers from the Met’s Counter Terrorism Command, supported by many other officers from across the Met and other forces across the UK, as well as other partners including Border Force and intelligence services," read a statement issued by Metropolitan Police.

Khalife was arrested on a towpath near Rowdell Road, Northolt by an officer who was part of the investigation team.

He was arrested on suspicion of being unlawfully at large, and taken to a west London police station, where he was further arrested on suspicion of escaping lawful custody.

"Khalife remains in police custody at this time and enquiries remain ongoing," police said.

Commander Dominic Murphy, Head of the Met’s Counter Terrorism Command, said: “The arrest of Khalife this morning is the culmination of an incredible effort by the investigation team, who have been working around the clock and have been supported by colleagues from across the Met and indeed the whole of the UK.

“But I must also thank the public and media for their tremendous support as well. We received well over 100 calls from the public following our various appeals and some of that information was key in helping us to focus our efforts and, ultimately, find Khalife," Dominic Murphy said.
