Police have stepped up patrols after a serial sex pest targeted two teenage girls in Worthing.

Several women have fallen victim of the man in and around the Homefield Park area during the past month.

The most recent was on Monday, just after 4pm, when two 13-year-old girls were approached by a man who exposed himself as they crossed the park by the tennis courts.

He is described as white, in his 20s, with short blond hair, carrying a backpack and wearing a green shirt and dark trousers.

Police are linking this incident to another at 6pm on the same day when a woman walking in the alleyway by the Co-Op store, close to the park, was approached by a man who threatened to expose himself.

He was wearing a cap, a blue top and jeans.

A police spokeswoman said there had been three other indecent exposures near the park.

An 11-year-old girl cycling home alone at 5.15pm on June 18 was approached by a male who took hold of her bike, preventing her from escaping.

He exposed himself but the girl pushed him away and cycled home.

This offence is linked to two other incidents in the park on June 19 when a man approached two females.

Detective Inspector Nigel Brown, of Worthing CID, said: "This man is causing distress."

Anyone with information can call police on 0845 6070999.
