British police say a scare at a busy London railway station was caused by an exploding e-cigarette.
British Transport Police released a statement saying they responded to the Euston railway station in north London around 7:40 p.m. local time after receiving reports of an explosion.
The Euston railway station was quickly evacuated and bomb-sniffing dogs were brought in to search the area.
People on social media described how crowds of people ran from the scene.
Police determined that the small, contained explosion was "caused by an e-cigarette which was in a bag at the station."
The train station has since reopened.
