YObs are being hunted by police after they hurled stones at a train passing through Rotherham.
The freight train, on its way to Cottam Power Station, near Retford, came under attack from offenders stood on the Blyth Road bridge, Maltby.
PC Richard Ward, of British Transport Police, said: “Three youths were seen running from the scene along the tracks and towards Mortimer Road.
“This is an example of a dangerous incident which left the driver understandably shaken. We urge those who think that throwing stones and other objects at passing trains is fun to consider the consequences of their actions, which could have been much worse.
“Anyone who trespasses onto the railway is taking a gamble with their own lives, as well as the lives of all the staff and passengers travelling on the trains.
“The railway is an inherently dangerous environment, with high speed trains and electric currents, and it should never be treated as a playground or somewhere to hang about.
The three youths were aged around 12-years-old, 5ft 7 tall and of a medium build.
One was wearing a red football top, one was wearing a black tracksuit and another was wearing a grey hooded top.
Anyone with information about the incident on Friday April 22 at 12.50pm should call 0800 405040 or Crimestoppers on 0800 555111.
