Alternative medicine practitioner Koh Nai Hock was charged on Thursday with 14 counts of allegedly sexually penetrating a woman with his finger.
The offences were said to have been committed between Nov 1 and Christmas Day in 2010 in rooms at the Grand Mercure Roxy Hotel in Marine Parade and the Ibis Hotel in Bencoolen Street.
It is believed that the alleged victim, who is said to be in her late 30s, was being treated by the 62-year-old Koh. If convicted, he could be jailed for up to 20 years and fined.
Koh, who is also known as Dr Bob Koh, does not have a medical degree and also faces one charge of advertising alternative treatment methods for cancer on the Internet. According to court papers, he had between May and July 2008 posted articles on the Internet that promoted his treatment of cancer.
The advertisements were titled: Alternative Treatment Stopped Cancer Cells from Growing Under 2 Weeks, An Open Letter to Doctors from Dr Bob Koh, and Doctor Bob Koh Updates on his 3 Recent Successes.
If convicted of contravening the advertising regulations of the Medicines Act, he could be fined up to $1,000 and jailed for up to a year.
Defence counsel Colin Phan told the district court that his client intends to claim trial to the sexual accusations.
There will be a pre-trial conference on March 10. Koh is out on bail of $20,000.
