Police are hunting the suspect of an unprovoked attack, after a shop assistant was hit over the head with a glass bottle.
The man, thought to be in his late teens, entered the Food and Wine Store in Camberwell Green at around 7pm on October 13 last year.
The suspect had an argument in the shop about his broken mobile phone and how dissatisfied he was with the service he had received there.
He walked out but returned half an hour later, walked straight up to the counter and hit the 25-year-old shop assistant over the head with a glass vodka bottle.
The victim was taken to hospital with head injuries.
The suspect is described as black, aged in his late teens or early twenties, 5ft 4″ tall with a gold or silver tooth.
He was wearing a purple and grey tracksuit top and light grey tracksuit trousers.
Detective Constable Tessa Lyle-Meller, from Southwark Police, said: “This is a dangerous individual who assaulted an innocent shop worker in an unprovoked attack. He needs to be located by the police. It is believed he lives locally, close to Camberwell Green.”
