PASSENGERS were forced to evacuate a bus in Glasgow yesterday after a fire was 'deliberately' started on the top deck.

The alarm was raised shortly after 10pm causing the bus to stop on Corkerhill Road at the junction with Braidcraft Road.

Twelve passengers exited the vehicle which is said to have been 'extensively' damaged as a result of the blaze.
