B.C.'s College of Naturopathic Physicians claims the owners of a Surrey clinic are improperly giving injections and claiming to be physicians.

The college has filed a petition in B.C. Supreme Court against the husband and wife who run South Point Natural Therapies. The couple was targeted by undercover investigators.

The investigators posed as patients seeking treatment from Sarge Sandhu and Sam Samrai.

The Surrey couple claim to be "Doctors of Natural Medicine" — a distinction the College of Naturopathic Physicians says might lead members of the public to believe they're naturopaths and licensed to deliver the injections both allegedly offer.

The undercover video, which was filed in court, shows Sandhu allegedly saying he has treated hockey players and UFC fighters.

He also allegedly says he cured Surrey Mayor Dianne Watts when she broke her back.

In an affidavit, the college's registrar says the couple agreed in 2012 not to hold themselves out as regulated doctors or to give injections and intravenous therapies.

The college alleges Sandhu and Samrai have violated these promises. When contacted by the CBC, Samrai would not comment, but described the allegations as lies.

None of these allegations has been proven in court.
