Description: CCTV cameras caught Francesco Hounye, a 22-year-old from Florida, being set upon by a gang of five Asian men on Commercial Road at just after midnight on Monday 17th June.
The group smashed a bottle into his face and then chased after him to continue their assault, repeatedly kicking and punching him - and police believe it happened because he was not a local.
Investigating officer Detective Constable Ben Mott said: "The victim has an Italian accent, his own style of dress and mannerisms and, when challenged by the Asian males, answered them back.
"They retaliated by grabbing the bottle and launching a vicious attack that has left him scarred for life. He had come to the UK to enhance his studies and has been left so shocked and horrified by what happened that he feels unsafe and is unsure if he wants to stay here.
"The CCTV footage is exceptionally clear and I believe the suspects to be local. I would ask people to please look closely at the faces of the attackers and help us identify them. I am positive someone would know who they are from looking at the footage."
