Members of hip hop group N-Dubz are being sought by police as potential witnesses in relation to an alleged rape, it was revealed today.

Witness: N-Dubz may be questioned

Officers want to speak to rappers Dappy and Fazer, whose real names are Dino Contostavlos and Richard Rawson, and have contacted the group's manager.

A 22-year-old man was arrested on suspicion of rape and common assault after an alleged incident at a Butlins holiday park in Skegness last Friday night or Saturday morning, Lincolnshire Police said.

The rap stars had played a gig at the holiday camp and an incident is alleged to have occurred after they went back to the accommodation with the suspect and three women in their early 20s from the London area.

One of the women said she was raped and assaulted and the other two said they were assaulted.

The suspect, named as Junior Edwards from Islington, north London, and thought to be a DJ, was arrested on Sunday at Skegness police station.

He was interviewed and released on police bail pending further inquiries, police said.

He is due to return to Skegness police station to answer bail on February 15 next year.

A police spokeswoman said: "Three further men from the Camden area of London are being sought as potential witnesses in relation to the allegations.

"Inquiries are continuing."

The gig by Mobo award-winners N-Dubz on Friday was organised by holiday companies 2wentys and Freestyle.

About 4,500 people who had gone on the companies' package tours in the summer attended the Naughty Reunion event at Butlins.

The reunions are held in different locations around the country, with the tag line "A weekend you won't remember but you'll never forget".

Other acts to perform included DJs Pete Tong and Judge Jules, a spokeswoman said.

She said: "2wentys can confirm it is assisting the police with their inquiries following an incident that allegedly took place in the early hours of Saturday 14 November at its reunion event in Skegness.

"While the investigation is ongoing we are unable to comment further."
