A knife-wielding mugger is suspected of carrying out four armed robberies over four days in the centre of Brighton.
The thug began his spree on Thursday (27 January) with the most recent street robbery taking place on Sunday (30 January) between 6.30pm and 7pm.
The descriptions given by the three men and one woman victim were similar and Detective Constable Mors O’Connor, from Brighton and Hove CID, said that the crimes may be linked.
Sussex Police said that the first robbery took place in New England Street on Thursday at about 2.45am when the knifeman approached a man and demanded property from him.
The victim handed over his wallet and mobile phone and the suspect left.
The suspect was described as white, about 6ft tall, of medium build and aged in his late teens to early 20s.
He spoke with a local accent and was wearing a black hooded jumper, with the hood covering his hair, and dark-coloured trousers.
