Police want to speak to a man in connection with an attack on a man in front of his family at Liverpool Street Station.
The 35-year-old victim was attacked on July 4 at the Central Line Bishopsgate exit just after 6.30pm, when he was about to make his way down the stairs to the tube with his wife and three children.
He went to pick up his two-year-old son from his buggy when another man who was making his way up the stairs tripped over him.
The man then attacked the father in front of his family and as passers-by shouted at the attacker to stop, he ran off.
It is believed the attacker boarded a Shenfield-bound station and got off at Harold Wood.
PC Alex Carter said: “We are issuing two images of a man who we believe has valuable information about the attack.
If you recognise the man pictured, contact British Transport Police on 0800 405040, or Crimestoppers anonmyously on 0800 555 111.
