Police sources confirmed on Friday that CCTV cameras at the Bank of Greece and another lender in central Athens recorded parts of Thursday morning’s car bomb attack.
The footage shows a Nissan Sunny being parked outside the central bank headquarters and the driver emerging from the vehicle wearing a helmet.
He then quickly got onto a Yamaha XT motorcycle that sped off, driven by another person.
Two people are also seen riding a second motorcycle. They are thought to have been the backup team.
The Nissan is then seen exploding.
Police have drawn parallels between the 74-kilo bomb and similar incendiary devices set by the Revolutionary Struggle urban guerrilla group in the past. No group had claimed responsibility for the attack by last night.
