A ban on school pupils using service buses in Glasgow has led to fears a recent spate of classroom violence is spilling onto public transport.
SNP ministers have been urged to act after First Glasgow stopped youngsters from Knightswood Secondary School from using local routes.
The move followed reports of alleged attacks on a driver and passengers, as well as vandalism and an emergency door being repeatedly activated.
Scottish Conservative education spokesman Stephen Kerr said it was a "shame" the bus company was forced to take the action.
