A man in his 20s was assaulted and robbed as he was walking home from Braintree town centre late at night.
The victim was at River View between 3am and 3.30am on October 4 when he was grabbed from behind, thrown to the ground and overpowered by two assailants.
One of them held him down while his accomplice rifled through his pockets and helped himself to the victim's brown River Island wallet containing about £90 and a driving licence.
Investigating officer DC Mike Pannell said: "This was a 'vicious robbery' but luckily the man was not badly injured, although he was badly shaken.
"We would like to hear from anyone who might have been in the area at the time and saw the suspects either hanging about or running away."
Anyone with information should contact DC Pannell at Braintree CID on 101 or call Crimestoppers anonymously on 0800 555 111.
