Six men have been sentenced for a string of robberies across south London which netted them more that £120,000.

The robberies all took place in south London, including Croydon, Crystal Palace and Mitcham, between June 2014 and May 2015.

The six men were sentenced at the Old Bailey on Friday, February 10 with three of the gang being handed life terms.

They were all found guilty following a trial at the Old Bailey.

Detective Constable Adam Barsby of the Met's Flying Squad said: "The gang targeted post offices and banks at opening time when they knew staff would be vulnerable to attack.

"They used violence and a firearm to terrorise staff and customers, who didn't put up any resistance.

"They showed no emotion, compassion or forethought for the victims in these crimes and acted purely out of greed.

"This gang terrified the victims of these robberies and I'm delighted to bring some closure to their ordeal with these sentences.

"Londoners are undoubtedly safer now this dangerous group of men are behind bars."
