Kaddour-Cherif's release due to 'mix up with warrants' - Prison Officers Association08:57

As we've been reporting, police are still searching for a second prisoner who was mistakenly released from HMP Wandsworth.

Brahim Kaddour-Cherif was set free on 29 October, after what the national chair of the Prison Officers' Association believes was an error when he returned from court.

“There should have been no way he was released, but it’s my understanding that there was a mix up with the warrants," Mark Fairhurst tells the BBC.

"So when that person returned from court, we didn’t actually have the authority to hold him in custody, because we didn’t have a further warrant which outlined those further charges.

"So somewhere along the way, there’s been a clerical error.”
