British Transport Police (BTP) have released a series of images of people they want to speak to in connection with the incidents.

Detective Sergeant Fintan Egan, the investigating officer, said: “The victim, a 17-year-old from Essex, had been out celebrating in London with friends and was making his way home on his own.

“As he made his way up the stairs towards the platforms, unprovoked, a group of between five and six men chased after the victim and attacked him with a bottle and a sharp object.

DS Egan said: “We’ve carried out a number of enquiries to try and establish the identity of this group, including speaking to witnesses and circulating images on police intelligence systems, but to no avail so far.
