BUKIT MERTAJAM, Malaysia - Police from Malaysia's Penang state will reportedly seek Interpol's help to trace eight of the 15 foreigners indulging in nudist activity at the Teluk Kampi beach of the state National Park.

Chief police officer Datuk Abdul Rahim Hanafi said that four of the foreigners were from Singapore, two from Myanmar and one each from the Philippines and India, local Bernama news agency has reported.

"We believe we can trace them soon so that they can assist in the investigation into the incident," he told reporters on Thursday.

The police have already identified seven Malaysians involved in the "Penang Nude Sports Games 2014". A video clip of the "sports carnival" uploaded on the social media, showed nine men and six women, all in the nude, painting their bodies, dancing and participating in some sports at the beach.

Abdul Rahim said the police were trying to trace the Malaysians, aged between 20 and 50, failing which they would publish their mugshots and identity so that the public could help trace them.

He also said that the police had recorded statements from 13 people over the "carnival", including those on patrol duty during the so-called games.

Abdul Rahim said the police had also identified the organiser of the games, a Malaysian in his 50s who was also a participant, as well as the individual, a foreigner, who made the video recording and uploaded it onto the social media.
