Police are appealing for witnesses after a man was attacked from behind with what is believed to have been a bottle.
The assault took place in Chelmsford High Street at about 12am on Saturday, August 9.
The victim, a 20-year-old local man, was left him with cuts and bruises to his head and arms.
Pc Chloe Lingane, of Chelmsford Police Station, said: "At this time we have not been able to establish any reason as to why the victim was attacked or any events leading up to the assault.
"This happened on a busy road and I am hopeful that passers-by may have seen what happened.
"Two women came to the aid of the victim and I am keen to speak to them about whether they witnessed anything.
