A man has been attacked twice after withdrawing money from a cash machine in Lewisham.
The man took himself to a hospital in south London with a number of injuries, including wounds, at around 12.50am on Friday, January 14.
Police established he had been assaulted outside the Halifax in Rushey Green at around 12.20am the same evening.
The victim told officers he had been punched by the suspect - who was known to him - while withdrawing money from a cash machine.
The suspect reportedly then left but returned a short time later carrying a weapon with a blade which he used in a second attack.
Later that day, a 42-year-old man was arrested on suspicion of causing grievous bodily harm and robbery after going to a south London police station.
He was subsequently bailed pending further enquiries.
Detective Constable Alan Jones, from the South East BCU, which covers Lewisham, said: “This was an unprovoked attack on a man in the street.
"Whilst we have made an arrest, I still need to speak with anyone who saw the assault.
"The victim has told us that there were other people in the area at the time, and I need them to come forward and tell me what they saw.”
Anyone with information is asked to call police via 101 quoting reference CAD 254/14Jan.
