This took place in Spain.
Spanish police agreed to placate a 'bank hostage' situation by allowing the radical to 'escape' uninhibited. He was allowed to walk out of the bank in the company of 2 hostages. The police provided him with a motorcycle and free access to the motorcycle.
Then, leaving the hostages behind, he was permitted to ride away down a clear roadway to make his escape. This whole incident, shown on CBS television, complete with news reporting in English, can be seen on this 55-second video clip.
