London police are searching for an attacker who hit a man in the head with a hammer before pushing him onto rail tracks.
The victim suffered a fractured skull and managed to run over to the opposite platform before the next service arrived at All Saints DLR station in east London on Monday night.
He is now being treated in hospital with non-life threatening injuries.
British Transport Police have today released CCTV images of the suspected attacker and Detective Superintendent Nick Sedgemore called it a “very concerning attack”.
“Enquiries have been underway since it occurred to locate the suspect and understand his motive. We ask anyone who knows the identity of the man pictured to get in touch,” he said.
Anyone with information can call police by texting 61016 or calling 0800 40 50 40 and quoting reference 670 of 29/07/19.
Meanwhile, in the German city of Frankfurt an eight-year-old boy was killed by a train on Monday after a man pushed him and his mother onto the tracks.
The mother was able to escape but the boy was hit as a high-speed ICE train was pulling into the station.
A 40-year-old man was arrested near the station, and police say there appears to be no connection between suspect and the victims.
German interior minister Horst Seehofer called the incident an “appalling act in the strongest terms”.
