A man was filmed as he was assaulted in Mansfield town centre. Police were made aware of a video showing the man being attacked in Queen Street on Monday (May 30) evening.
The victim and any other witnesses who have not yet made contact are being encouraged to come forward. Chief Inspector Christopher Sutcliffe, of Nottinghamshire Police, said: “This is an appalling display of violence and we are working hard to identify all those involved so they can answer for their actions.
“As part of our investigation we are keen to speak to the victim and we urge him or anyone who knows him to come forward. Similarly, we would like to speak to any other people who either witnessed the attack or came to the aid of the victim.”
