Ontario Provincial Police have located the second vehicle believed to have been driven by a suspect accused of sexually assaulting a 16-year-old boy and chaining him up in a home on Nova Scotia's South Shore.

It is believed the car belongs to Wayne Alan Cunningham, 31.

The grey 2003 Hyundai Elantra was found abandoned on a logging road in Longlac, Ont., about five kilometres from where 47-year-old David James Leblanc, another suspect in the case, was found disoriented and barefoot earlier this week .

Police say Leblanc, who was taken into custody, is still not fit to be transported to Nova Scotia for "medical reasons."

Boy in chains

Leblanc and Cunningham are facing charges of forcible confinement and sexual assault.

Police say the two men held a teenaged boy for about two weeks in Upper Chelsea, Lunenburg County.

An arrest warrant for the pair says, "Over the course of several days these two men forcibly confined and sexually assaulted [the teen]" and that "the two men were talking about trying to sell him."

The teen escaped from the house and walked more than one kilometre to another home to ask for help.

The teen had chains wrapped around his wrists and ankles and was wearing nothing but a hooded sweatshirt and a hat when he arrived on Terry Frauzel's doorstep.

Frauzel told CBC News he cut the chains off the boy and drove him to a house in Bridgewater.

The teen was later treated in hospital and police say he is now safe.

Suspect still at large

Police in northern Ontario say they are still searching for Cunningham.

"What we have determined is not only is it the vehicle in question that was located, but all we all know is that it was unoccupied. There is a ground search that is continuing as we speak," said OPP Sgt. Anne McCoy.

Cunningham is described as five feet three inches tall, 119 pounds with brown hair.

He's known to dress as a woman.
