A suspect has been arrested for attempted murder after 17 people were injured in a knife and fire attack on a train in Tokyo that was carried out by a man wearing a Joker costume.

Witnesses told public broadcaster NHK how petrified passengers had fled to adjoining carriages and jumped out of windows during the attack, which occurred on Sunday, when the Japanese capital was full of Halloween revellers, many in costume.
