Members of a gang who used drones to smuggle contraband into prisons including Wandsworth have been jailed for 22 years.

The group was so prolific officers believe it was responsible for the majority of airdrops at jails across London.

An investigation was launched in December into the drugs and mobile phones that were being delivered in the middle of the night.

This led to the arrest of the seven-person team which consisted of drone pilots, co-pilots, taxi drivers and lookouts.
