A yob threatened a bus driver, headbutted his protective cab and pulled its door off its hinges during a row in Sheffield.
Detectives have issued a CCTV picture of a boy they say could hold vital information after violence flared on the bus as it travelled along Chaucer Road, towards Deerlands Avenue, Parson Cross.
The boy became involved in a ‘dispute’ with the driver and headbutted the protective cab where he sits.
He then pulled the door of the cab off its hinges, causing around £800 worth of damage, before grabbing the driver’s arm and attempting to pull him out of the cab.
A South Yorkshire Police spokeswoman said: “Extensive enquiries have already been made into the circumstances surrounding the incident, which happened at around 3pm on Friday, April 11, and now officers are appealing to the public to identify the person.
“It is reported that a youth got onto the number 35 bus in Hillsborough. As the bus approached Deerlands Avenue, at the junction of Chaucer Road in Parson Cross, he is then reported to have had a dispute with the driver, before headbutting the protective barrier surrounding the driver’s cab.
“He then pulled the door of the cab off its hinges, causing around £800 of damage, and grabbed the bus driver by the arm before attempting to pull him out of the cab.
“The suspect then made off on foot, towards Chaucer Road. The 48-year-old bus driver, from Sheffield, was left shaken but otherwise unhurt.”
The youth was white, with short dark hair and was wearing a white T-shirt with a dark zipped-up hooded top.
Police in Sheffield also want to trace a man and a woman over an assault on a passenger on another bus.
A 59-year-old man was sitting on the lower floor of a number 48 double-decker travelling from High Street, Sheffield, to Shiregreen, when he was assaulted at around 6.40am on Tuesday, May 6.
Officers have released CCTV images of a man and woman they believe may be able to help with inquiries.
