Officers in Bournemouth are appealing for witnesses and anyone with information to come forward after an assault in the Charminster area.
The incident occurred between 11pm and midnight on Friday 21 February 2014 on Shelbourne Road.
A 32-year-old local man was walking together with a male friend from Charminster Road into Shelbourne Road when he was attacked by a group of men.
The five offenders assaulted the victim leaving him with serious injuries including bone fractures and a broken nose. His friend escaped uninjured.
Detective Constable Natalie Selwood, of Bournemouth police, said: “This is believed to be an unprovoked attack.
“The victim’s serious injuries mean that he will be off work for a number of weeks.
“It is possible there were other people around in the area at the time who may have witnessed this incident – I urge them to come forward.”
The five offenders are all described as white teenagers. One of them was notably taller than the rest of the group – approximately six foot two inches. Two of the group were wearing baseball caps.
DC Selwood continued: “I am interested to speak to anyone who may have information that may assist with the investigation. I would ask them to call Dorset Police in confidence as soon as possible.”
Witnesses and anyone with information should call Dorset Police in confidence on 101, quoting incident number 22:440. Alternatively, call the free and anonymous Crimestoppers line on 0800 555 111 where mobile phone tariffs may apply.
