Maricopa County Sheriff Joe Arpaio says he’s frustrated after a third death threat from a 16-year-old in Canada. The sheriff says the threat was posted on a social media site this week after the teen was released by a judge, following a similar threat last month.

“I’m not too concerned about myself but he’s threatened to kill my grandkids, burn the house down, and he continues on, and nothing’s done in Canada,” Arpaio said.

The sheriff says the Royal Canadian Mounted Police are doing the best they can but the teen continues to be released by the court system.
