Brandon Crisp, 15, is seen in this undated police handout photo.
Volunteers post missing posters for the teen who disappeared on Thanksgiving.
Brandon is believed to have a yellow and grey back pack similar to the one pictured above.
The parents of a missing Barrie, Ont. boy believe his disappearance stems from an argument over his "fixation" with a video game, police say.
Brandon Crisp, 15, was last seen more than a week ago after fighting with his parents, who revoked his privileges to play the Xbox game "Call of Duty 4: Modern Warfare."
It wasn't the first time they had banned him from playing the first-person shooting game. But on Monday, October 13, "he became upset and left home," Sgt. Dave Goodbrand told CTV.ca on Tuesday.
He was last seen riding away from home on his yellow and black mountain bike at about 3 p.m.
"Since that day he left home and has not been seen," Goodbrand added.
Police have been tracking his user name on the online Xbox account but "he has yet to log on from another location."
Goodbrand described the teen as "obsessed with the game."
"Over the last couple of years, Brandon has become less involved in sports and extremely involved in 'Call of Duty 4.' They have found him waking up in the middle of the night playing it," he said.
On Tuesday, police hope to conduct a more thorough search of the area of the 2nd Line of Oro and Ridge Road, where Brandon's abandoned bike was spotted.
Media reports suggest Brandon sought directions to the nearby township of Oro-Medonte before riding away on his bicycle.
The same day, a local resident found a similar bike abandoned in the area of 2nd Line of Oro-Medonte and Ridge Road. By the weekend, the bike was missing, but police have since confirmed it was Brandon's.
While nothing has come so far of the extensive air and ground search, police are hoping their efforts will yield new leads.
They are appealing to locals to search their residences and cottages for any sign of the missing teen.
Brandon is described as male, white, 100 pounds, 5'2", short sandy blond hair. When he was last seen, he was wearing a yellow and grey jacket, a grey American Eagle-brand hoodie, blue jeans, white runners with a camouflage stripe on the sides. He may also be carrying a yellow and grey back pack.
Anyone with information is asked to contact Barrie police at 705-725-7025.
And besides, what the hell did he think would come of this? Now he's on the run, he apparently hasn't logged on to play the game since he's been on the run..... so now he's missing out on all this time he could be playing the game.
Clearly he's not that addicted, he's just a little brat who always wants to get what he wants..... considering his parents gave him a game he shouldn't have at that age in the first place.
Check this out:
^ See that big M on the bottom left? Yeah, right above that it says 17+ for age.... the kids 15.... technically he shouldn't have it in the first place.
Perhaps the parents shouldn't have left the game in his room and left it out in the living room so they could have more control over how much he plays it.
