HAYWARD -- A former Dublin physician was sentenced Wednesday to seven years and four months in state prison for committing sexual crimes against four men and a 13-year-old boy.

Tony Shiu, 40, pleaded no contest on May 14 to eight felony counts and one misdemeanor count, and was sentenced in Alameda County Superior Court in Hayward by Judge Henry Ramsey.

The felony charges to which he pleaded are three counts of sexual battery, two counts of administering a controlled substance, two counts of poisoning and one count of lewd and lascivious acts on a minor.

He also pleaded no contest to a misdemeanor count of sexual battery.

Alameda County Sheriff's Sgt. Herb Walters, who investigated the case, said detectives who searched Shiu's home in Dublin on Sept. 8, 2006, found about 450 digital photographs of at least 10 exposed men in medical settings who appeared to be unconscious.

The arrest warrant for Shiu alleged that he drugged two men on Aug. 18, 2006, and sodomized one of them.

The two men alleged that they began a night out at Shiu's home and woke up the next day, on Aug. 19, with no recollection of the night before. Police said one of the men had never met Shiu previously, but the other was Shiu's friend and patient.

Shiu fled the Bay Area in September 2006 after learning that authorities were investigating him.

Alameda County investigators tracked Shiu to Taiwan, where he had been living under an assumed name. He was arrested at San Francisco International Airport on May 29, 2008, after being deported from Taiwain.

Shiu practiced private general internal medicine. The Medical Board of California suspended his license in July 2007.
