Officers from Islington are appealing for witnesses and information following the recovery of two drones carrying mobile phones and drugs in the vicinity of HMP Pentonville.
Over the weekend of Friday, 12 to Sunday, 14 August, officers from the Caledonian Neighbourhoods Policing Team and the Met's Special Constabulary carried out patrols in the area of the prison as part of Operation Airborne.
Operation Airborne has been set up to deter and catch offenders attempting to deliver contraband into the prison.
During the early hours of Saturday, 13 August, officers observed a man acting suspiciously close to the prison. On seeing police, he ran from the scene, dropping two bags containing a quantity of Class B drugs and mobile phones. He evaded arrest.
The following day, officers recovered a drone after tracking it flying over HMP Pentonville, before it crashed. Later in the day, they were alerted to another drone being flown towards the prison. The low flying drone was stopped mid-flight by an officer and a package containing a large quantity of drugs and two mobile phones was recovered from it.
Detective Chief Inspector Steve Heatley, said: "These recovered drones carried a substantial amount of Class B drugs, legal highs and a large quantity of mobile phones; we are able to intercept them thanks to the vigilance of officers and the public. We work closely with the prison service to gather intelligence in order to carry out proactive operations to arrest and prosecute such offenders. I would urge anyone with information about these events to contact the police or Crimestoppers to help us to identify those responsible."
Anyone with information is asked to contact police on 101 or call Crimestoppers anonymously on 0800 555 111.
No arrests have been made.
