Overheating workman's drill causes smoke alert train evacuation
A commuter train was evacuated after a workman's drill overheated, British Transport Police (BTP) said.
Officers were called to Dalston Kingsland, east London, at 7.10am on Wednesday following reports of smoke on a train.
A "number of people" suffered minor injuries and were treated at the scene.
Police said the incident is not being treated as suspicious.
A BTP spokeswoman said: "We were called at 7.10am today to Dalston Kingsland to reports of smoke on a train.
"Several passengers left the train as a result of the smoke.
"Fire service also attended and established that a workman's drill had overheated and was smoking.
"A number of people have sustained minor injuries and were treated by the ambulance service at the scene.
"This incident is not being treated as suspicious at this time."
Duncan Cross, deputy director of London Overground, said: "At around 7.14am today there was an incident involving a faulty drill that was being carried to work by a customer at Dalston Kingsland. The train was evacuated and the emergency services attended.
"We would like to apologise to customers who were on board and to our customers whose journeys have been disrupted."
Video from the scene posted on social media showed people standing alongside the tracks and platform at the London Overground station.
One passenger tweeted that there had been "sheer terror" and "panic" on board the train.
A London Ambulance Service spokeswoman said they were called to the station at 7.36am.
She said: "We sent four ambulance crews, a single responder in a car, an incident response officer and our Hazardous Area Response Team (Hart) to the scene.
"We are treating a small number of patients at the scene for minor injuries."
London Fire Brigade (LFB) said firefighters had extinguished the drill's battery after it started smoking.
A tweet by London Overground said it was believed a customer's battery had "exploded" but a spokesman said this was under investigation.
An LFB spokeswoman said: "Firefighters have dealt with a small incident on a train at Dalston Kingsland station this morning.
"A workman's drill had overheated and started smoking. Firefighters extinguished the battery and placed it in a bucket of sand.
"The station was evacuated."
