A Halton paramedic has been arrested in an alleged October 2015 incident involving an adult female patient inside an ambulance. Tad Nelson, 57, of Dundas, has been charged with sexual assault and voyeurism, according to a Halton Regional Police news release. He appeared in court in Milton Friday.

Nelson had been a Halton paramedic since 2000 and was put on unpaid leave after being charged, until the completion of a “thorough internal investigation,” said Halton Region spokesman John Winkels. “We are deeply disturbed by the charges against this individual,” he said.

“The public can be assured we are fully cooperating with police and continue to do so throughout this investigation. We are also conducting a thorough internal investigation of this matter.”

Anyone with information is asked to contact Det.-Const. Matt Cunnington at 905-465-8978 or Det.-Const. Alanda Prescod at 905-465-8977, of the Halton Regional Police Child Abuse and Sexual Assault Unit.
