Ottawa police have charged Charles Martina, 65, of North Plainfield, N.J., with one count of aggravated sexual assault resulting from alleged incidents between July and September 2006.

The complainant came forward in May 2012 and an investigation began then. Police obtained the accused's medical records from the U.S., which took a few months, before laying the charge.

A warrant has been issued for Martina's arrest and Ottawa police Insp. John Maxwell said Martina is aware of the charge, but he believes the man is unlikely to ever face Canadian courts.

Maxwell believes Martina will never return to Canada.

The man is believed to have entered Canada frequently over many years for fishing trips in the Ottawa Valley up the Highway 17 corridor to Northern Ontario. Ottawa police have contacted other police forces in Ontario to inform them of the criminal charge.

2 charges in alleged N.J. incidents

Martina was also charged in New Jersey in the fall of 2011 for allegedly having sex with two women, 45 and 61, without disclosing his HIV-positive status, according to multiple U.S. media reports.

One woman was allegedly involved with Martina from May 2008 to June 2010 while the other from February to August 2011, reports said.

Ottawa police are also asking anyone who had sexual contact with Martina to contact Ottawa police at 613-236-1222, ext. 5407 and seek the advice of their health care provider.

Martina is said to have retired from the police department in Plainfield, N.J., as the head of its narcotics and vice bureau in 2000 after serving 28 years on the force.
