BRIDGEWATER, N.S. -- John Leonard MacKean insisted he only touched a captive boy's penis with his hand.Follow @Canoe
The portly 64-year-old is charged with sexual assault and communication for the purposes of sex with a minor.
A jury watched MacKean's four-hour police interview tape Wednesday.
He has plead not guilty.
At one point in the footage MacKean stood up from his chair, leaned over and simulated with his hand what he said he did.
"I thought he 21, 22 ... I didn't think it would be a problem," MacKean told Cpl. Luc Cote on the video.
"He looks 12," Cote responds firmly. "I have a son who's 12 and he looks one day older than him."
The victim was 16 when he was kidnapped from Halifax, driven to a remote shack, chained up and raped by two men for 10 days in September 2012 before he managed to escape through a boarded window.
One of the kidnappers pleaded guilty and is in jail. The other is dead.
