CCTV images of two men have been released after a man was punched and robbed in a late-night attack.

Police want to speak to two men pictured walking through an underpass following an assault in Archer Road, Stevenage, between 11.30pm and 11.55pm on Monday.

A man in his 20s was assaulted by two offenders who then demanded the victim to hand over his personal belongings, which included a Samsung Galaxy mobile, iPod Nano, Timberland reading glasses and some keys, before he was able to flee.

Anyone with information should contact Detective Sergeant Phoebe Butfoy on non-emergency number 101, or Crimestoppers anonymously on 0800 555 111.
