Police are concerned about a man who took his clothes off in front of two girls on a public beach.

The girls, aged 11 and 13, were sunbathing on Southwick beach when a man approached, spoke to them and then took his clothes off.

He sunbathed on the beach before putting on trunks and going into the sea for a swim.

Inspector Chris Drew, of Shoreham police, said: "We would like to speak to him to advise him about his behaviour."
