A serial sex attacker in Brighton and Hove must be caught before he threatens another woman and maybe even kills her.

The man, armed with a knife, has attacked ten women, mainly in central Brighton, since October, raping one of them.

Now a man of similar description has threatened and raped a 20-year-old woman behind the King Alfred Leisure Centre in Hove.

This man is so reckless and frequent in his attacks that he is bound to make a mistake and be apprehended in the end. The trouble is he could cause more immense fear and agony before that happens.

Witnesses are urgently needed to help police build up a picture of the man and anyone who has any information, no matter how minor, should waste no time in calling detectives.

In the meantime, women out alone at night in Brighton and Hove should be even more vigilant than usual. In particular, they should not accept lifts in cars from drivers they do not know.
