Police hunting a sex attacker dubbed the Beast of Bognor were continuing to question a 28-year-old man this weekend.

The suspect was arrested in Troon, Scotland, and brought to Sussex on Friday.

Sussex Police refused to identify the man but said their search for a Romanian illegal immigrant called Petru Samfira had been halted.

One woman said she was raped and three others reported they were indecently assaulted in or near the holiday resort.

A source close to the inquiry said the man, being questioned at Chichester police station, was Samfira, who had been working for a sub-contractor at the Rolls-Royce factory at Goodwood.

A Sussex Police spokesman said: "The man in custody cannot be identified but we wish to stress our appeal to find a named person has been withdrawn.

"The man may be held for some time and an identity parade may be held. If he is not charged, he may be released on bail."

Last week, police released an electronic photofit of Samfira, believed to be the same man caught on CCTV riding away from the Butlins camp at midnight on Wednesday last week.

The cyclist was spotted in bushes close to the perimeter fence by security guards who have joined with police to step up patrols of the area. The man was challenged but fled.

Officers searched a mobile home at the Riverside caravan park in Bognor where Samfira had been living.

He is being quizzed over the sex attacks, the first of which happened on August 10 when a woman said she was raped just inside the grounds of the Butlins camp.

The second attack was four days later when a woman told police she was indecently assaulted, again just inside the perimeter of the camp.

On August 18, a third woman reported to police that she too had been assaulted by a man while Sussex Police said the fourth attack in the early hours of Tuesday happened in the grounds of the camp when a man grabbed a woman, kissed her and then pushed her on to a bench. She managed to struggle free.

One of the victims was a guest at the camp. The other three were all local.
