A police hunt is underway after a man was left with a bleed on the brain following a violent assault in the City of London earlier this year.
The man was attacked outside Monument Underground station, near the financial district, at around 2am on April 4.
Nearly four and a half months after the incident, police continue their investigation, but no arrests have been made.
Now, City of London Police has published CCTV footage of a man they would like to speak to.
The image shows a man with short dark hair and a beard. He appears to be wearing a black long sleeve shirt or jumper.
Anyone with information has been urged to call 020 7601 2222 ref 93321.
Anonymous reports can be made to Crimestoppers via 0800 555 111 or the charity's website.
