Do you really know who's living next door to you? Neighbours in Pickering may have been surprised about the man beside them - he was a convicted sex offender who wasn't supposed to be in Canada at all.

Durham Regional Police have revealed they arrested 36-year-old Jeffrey Roberts at a job site in Toronto last Friday. He'd been here at least five years, and was taken into custody while he was working installing shingles on roofs.

Roberts had been convicted in Wichita, Kansas back in 1999 on a charge of committing aggravated indecent liberties on a 15-year-old girl.

Part of his sentence required him to register as a sex offender and report to authorities three times a year. But in 2004, he vanished, making his way past the border and into the GTA. He eventually settled in Pickering.

Cops got wind of his travels and authorities down south contacted their counterparts here to try and find him. They finally tracked him to his home and began tailing him, closing in on him at work, where he'd be the least likely to be able to flee.

The convicted felon has been ordered back to the U.S. where he will be put back in jail for violating the conditions of his release. There's no indication that Roberts ever attacked anyone in this country, but those who lived near him are stunned that he's been in their neighbourhood all these years and they never knew it.
