A gang of violent armed robbers have been found guilty of raiding 10 banks and post offices during a £120,000 ($151,000, €141,000) crime spree lasting a year.
The six men terrorised staff and customers across south London during the raids between June 2014 and May 2015.
In total, the gang targeted eight high street banks owned by Barclays, HSBC, Natwest and Lloyds TSB, as well as two Post Offices.
Detectives said they would strike at opening time when they knew staff would be vulnerable.
So prolific were the robbers that police said the 2014 Christmas period saw them target three banks in just one day.
The men were convicted for a string of offences at the Old Bailey on Wednesday (25 January). They will be sentenced at the same court on 10 February.
Five of the gang had already been convicted of a £15,000 robbery of a Post Office in Croydon High Street, south London, in May 2015, during which two female staff members were pistol-whipped.
DC Adam Barsby, of the Met Police'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."
Gary Katabarwa, 29, of HMP Belmarsh, was convicted of nine counts of conspiracy to rob, one count of possession of a firearm with intent to cause fear of violence, and one count of money laundering.
Shane Perry, 34, of HMP Belmarsh, was convicted of five counts of conspiracy to rob, one count of possession of a firearm with intent to cause fear of violence and one count of money laundering.

He pleaded guilty to one count of conspiracy to rob and one count of money laundering at the beginning of this trial and awaits a date for sentencing.
