This is the moment a naked German tourist is arrested after riding around on a Segway while masturbating in public - after losing a BET.

Jochen Dieter Pastetzky, 56, told officers that he had been gambling with friends in Pattaya, Thailand, last night when he lost a game. The perverted holidaymaker then shocked locals as he scooted around the streets without clothes.Stunned resident Korn Sawasmongkol, 32, said he saw the man holding his erect penis and pleasuring himself on his single-wheel electric machine. The apartment block security guard called police who arrived and pounced on the naked man in the Nongprue district of the city.

He was photographed in nothing but a pair of red trainers and silver army-style helmet helmet carrying his groceries in his free hand while the other held his manhood.

Korn said: ''The man was 'helping himself' as he went round on his scooter. He was doing this and showing his penis to tourists.I was at the gate of the condominium block and saw him do this. I called police and they chased him.'' Officers received a call at 10pm and arrived shortly after near the Pratumnak Hill apartments.

Lieutenant Colonel Satsak Pinthong from Pattaya Police Deaprtment said: ''We have taken control of pictures of him masturbating without any clothes on and a report will be made to prosecution him for obscenity. We explained that this is inappropriate behaviour in Thailand.'' The tourist faces a fine of 5,000TH.Lieutenant Colonel Satsak Pinthong said that had also asked Jochen to make an apology to villagers who he exposed himself to.
