A Montreal man whopleaded guilty to victimizing two Alberta girls through luring and extortion was sentenced to nine years in prison Tuesday.

Outside an Edmonton courtroom, Crown prosecutor Diane Hollinshead said Joshua Innes's nine-year sentence will hopefully send a message.

"The judgment reflects the court's view of the seriousness of this type of offence. We are seeing more of them. This particular judgment shows the court recognizes the seriousness of the internet and offences that occur on the internet."

In May, Innes, 25, pleaded guilty to two counts of child internet luring, two counts of extortion and one count of distributing child pornography.

The charges stemmed from two cases, involving a 14-year-old Airdrie girl and a 13-year-old Edmonton girl.

Innes posed as a 16-year-old girl named "Nikki" from Calgary to get the two girls to perform sexual acts for him over their webcams. He then threatened to post the images on the internet unless they did other sexual performances.

In May, the mother of one of the girls warned other parents to restrict their children'saccess to the internet.

The woman, who can't be named to protect the identity of her daughter,had even invited police officers to a youth group she had run to talk about safety matters.

"No matter how close you think you are with your kids and how much you've talked about internet safety, I just want to let the other moms and dads know out there that they should make sure the computer is in a high-traffic area [and] that there's limited use of webcams or no webcams at all."
