A British man is being questioned by police over the alleged rape of an 18-year-old woman from New South Wales in Bali for schoolies. 
Denpasar crime division police chief Reinhard Habonaran Nainggolan said the teen filed a report with police on Friday against the 25-year-old British citizen.
She told police she had met the man at Bali nightclub Sky Garden, and  the pair went back to her hotel.
"Both chatted for a while ... went to her room and had sex," Mr Nainggolan said.
He said police found the man at Sky Garden and detained him.
"Based on a brief interrogation, he claimed the sex was consensual," he said. 
"He also claimed she said 'oh, you are not good'. He said: 'well in that case, let's stop.'"
Mr Nainggolan said police could not yet conclude rape had occurred, with the investigation still underway. The British man was being questioned but had not been named as a suspect.
Mr Nainggolan said a medical examination had been requested.
"If it shows no sign of violence the report will be dropped. We have 24 hours."
Mr Nainggolan said the man was still seeking a lawyer to represent him.
"He said this is his first time holidaying in Bali with friends."
