A man has been robbed of his wallet and iPhone in Regency Square, Brighton.
The mugger was standing in a doorway as the 26-year-old local victim walked up Cannon Place through Russell Square.
He followed the victim then grabbed him around the throat and threatened him before stealing his wallet and phone.
The suspect made off towards Russell Square.
Detective Sergeant Lex Witek said: “This is a frightening attack for the victim and thankfully he has been left with only a tender throat.
