POLICE are appealing for witnesses to an incident where a bus driver was threatened with a knife and robbed of his takings.

The two Asian youths robbed the driver of around £70 in the attack a week ago today in Blackburn.

The attack happened at 7.20pm, after the driver had picked up the two youths from the gates of Queen's Park and was dropping them off in Pringle Street.

As they were about to get off, one of them produced a knife and demanded the takings. The pair got away with around £70.

The driver, although shaken, was able to drive back to the bus station to raise the alarm.

The main offender is described as Asian, in his early 20s, around 6ft tall and clean shaven. He had short, black hair and had a distinctive, crooked nose. He also had a one inch-long vertical scar coming down from below his left eye.

The other offender is about 5ft 10ins tall, with short black hair and wore a black, thigh-length coat.

If you can help, ring DC Ramsden on 01254 353565.
