VANDALS who threw a piece of metal onto a railway line in Southampton have been slammed by Network Rail.

The firm has revealed details of the incident, which happened in the St Denys area of the city.

The piece of metal, which is believed to be a lamp case from a spotlight, was hurled onto the track and caused damage to a train at about 5.35pm on Sunday.

Mark Killick, route director at Network Rail Wessex, said: “This reckless act caused delays to passengers – many of whom are critical workers – and damage to the railway and train. Fortunately, no one was injured.

“I would urge anyone with information to come forward and contact the British Transport Police.”

British Transport Police are investigating the incident and anyone who has information is being urged to text BTP on 61016 or freephone 0800 405040, quoting incident number 281 of June 7.

Inspector Andy Jackson from the British Transport Police who is embedded on the Wessex route, said: “This is a mindless act of vandalism by the persons involved, resulting in damage to the tracks and the train and passengers being trapped on trains.

“Obstructing a train by either throwing or placing objects on the line is a very serious offence carrying a maximum of two years in prison. We’ll review CCTV of the incident and will actively pursue those responsible to ensure they are held accountable for their actions.”
