A 16-year-old boy was arrested in the Pembroke, Ont., area after an overnight home invasion and kidnapping in Quebec, police say.

One suspect remains at large.

An older couple were forced out of their cottage home overnight in Bouchette, Que., near Maniwaki, by two suspects.

The suspects drove them to a barn about 2 ½ hours away and left them tied up, according to Quebec provincial police.

The suspects used the couple's vehicle to take them to the barn, somewhere near St. Joseph Street in L'Isle-aux-Allumettes. The suspects fled after tying them up.

The couple — the man is in his 60s and the woman is in her early 70s — later managed to get themselves untied and out of the barn, police said.

A passing motorist noticed the distressed couple on the side of the road and stopped to help. They were in shock and were taken to hospital with minor injuries, police said.

Couple's vehicle found abandoned in Pembroke, Ont.

Their vehicle was found later Saturday morning, at about 9:30 a.m., abandoned in the area of Pembroke, Ont.

The suspects were originally described by police as two English-speaking young men, both wearing scarves over their faces.

The first was believed to be about 18 to 20 years old, standing at about six feet tall and weighing about 170 pounds. The second was believed to be about 20 years old, standing at five feet seven inches tall, and weighing about 150 pounds.

One of them was carrying a handgun, police said.

The couple were still being cared for in hospital later Saturday morning and hadn't yet been fully interviewed by investigators, police said.

The boy was arrested by Ontario Provincial Police sometime after the abandoned vehicle was found. He is being transferred to Quebec, where investigators are set to interrogate him, police said.

The investigation continues.
