Scottish prosecutors say they will not charge the driver of a garbage truck that ran out of control and plowed into shoppers on a busy Glasgow street, killing six people.

The driver Harry Clarke has told a newspaper he fell unconscious in the vehicle and cannot remember anything about the Dec. 22 accident.

Scotland's Crown Office said Wednesday that neither Clarke nor Glasgow City Council should face charges.

The office said that "despite its catastrophic consequences there is no evidence to suggest that the driver's conduct at the time amounted to a breach of the criminal law."

Prosecutors said an official inquiry into the crash should be held as soon as possible.

Patrick McGuire, a lawyer for some of the victims, said his clients welcomed the announcement of an inquiry.
