CCTV shows man pushing trolley on to Euston railway tracks
CCTV footage has revealed the moment a train struck a suitcase trolley deliberately pushed on to tracks at one of the UK's busiest stations.
The video also shows the offender walking along the platform after pushing the trolley on to the line at Euston station in central London.
The incident happened at about 09:00 BST on Tuesday August 6.
British Transport Police (BTP) said no-one was injured but they were keen to speak to the man in the video.
Insp James Tyrrell, of BTP, said: "As shown in the footage, he approached a suitcase trolley, which was on the platform, and suddenly pushed it on to the tracks, before walking off from the scene.
"A short time later, a train arriving into the station struck the trolley, luckily causing no significant damage."
Mr Tyrrell added: "We are unsure as to why the man deliberately pushed the trolley on to the tracks before walking away, which is why we are keen to trace him and speak to him about his dangerous actions.
"If the train had been travelling at speed, it could have caused serious damages to the tracks, train and anyone who may have been close by.
"The image of the man is clear - if you recognise him, I'd urge you to come forward."
