Arrest warrant issued for B.C. 'bedroom dentist'

A B.C. Supreme Court justice has issued a warrant for the arrest of a man accused of running an illegal dental clinic in Burnaby, B.C.

The warrant for the arrest of David Wu, also known as Tung Shen Wu, was issued Monday morning and is valid only in B.C., but authorities say it’s not clear if Wu is still in the province.

An investigator with the College of Dental Surgeons of B.C. has apparently been looking for Wu since last Thursday.

The college is seeking an injunction against Wu, and wants to see him jailed for working without a licence.

Last week, the college issued a public warning after it was revealed Wu, 62, had apparently been operating an illegal clinic out of his Burnaby home. Anyone who has been treated by Wu during the past 20 years is being advised to be tested for hepatitis B, hepatitis C and human immunodeficiency virus (HIV).

CBC News obtained video of a College of Dental Surgeons of B.C. raid at the clinic, which revealed dirty and disorganized conditions.

The video shows the living room of the house was set up as a waiting room and the dental practice itself was run out of an apparently filthy bedroom, with a dirty floor and shelves covered with dust and debris.

There was no evidence of any source for sterilized water.

The College of Dental Surgeons of B.C. is expected to release more information at a news conference Monday afternoon.
