Four teenagers have been arrested after a man suffered a broken nose and ribs in an unprovoked daylight attack on a Tube station platform.
Police arrested three 15-year-old girls and a boy, also aged 15, and are now appealing for witnesses after the assault at Colindale Underground station.
Officers were called to the scene at about 5.50pm on Monday, May 25.
The victim was said to be looking at a map on the platform when a train arrived and a group of youths got off.
One of the group allegedly kicked the victim's heel as he passed them and, when he challenged them, the situation escalated with the group said to have punched and kicked the victim.
They then all left the station while members of the public administered first aid on platform.
He went to hospital and was found to have suffered a broken nose and broken ribs.
British Transport Police responded and arrested four people – three girls and a boy, all aged 15 – on suspicion of grievous bodily harm.
They all remain on police bail.
Now, British Transport Police have released photos of three people they would like to speak to.
Anyone who recognises them is asked to text BTP on 61016, or call 0800 40 50 40, using the reference 563 of 25 May.
Information can be given anonymously to Crimestoppers on 0800 555 111.
