A BUS company has hit out at "mindless vandalism" after three of its fleet were left with smashed windows this afternoon. 

First Bradford's 620 service was forced to terminate at Rooley Lane Asda, due to the incident on Bierley Lane. 

A spokesperson said it involved two to three youths, but the bus service is now back to normal. 

“This mindless vandalism is endangering our drivers and customers and disrupting the lives of local people trying to get to and from work and make necessary trips," they said. 

"It is reckless behaviour and needs to stop before someone is seriously hurt or worse. 

“The safety of staff and customers is our highest priority and will work closely with the police to investigate these incidents including the use of on board CCTV footage to help identify the individuals involved.”
