Police have set up a cordon around Peterborough Prison this evening, Friday, to deal with an "ongoing incident."
A police spokesman was not able to confirm at this time what had happened, but multiple units are at the scene and officers told the Peterborough Telegraph it was an "ongoing incident at this time."
The bomb disposal unit is also in attendance and a member of that team has made his way towards the prison in a protective suit according to our contact at the scene.
Eyewitnesses at the scene say the incident seems to be led by the RAF Explosive Ordnance Disposal team and a explosives robot has been sent in to the prison.
The Peterborough Telegraph understands from staff at the site that the investigation centres around the engine bay of a vehicle parked within the prison complex. This is yet to be confirmed by the police.
The prison is currently 'masked' off on all sides with what is a substantial cordon.
