Vice President Joe Biden's security perimeter suffered a breach while he attended the Winter Olympics, according to a report.

A mentally unstable man obsessed with Biden (shown here with his wife Jill, left, and Valerie Jarrett) and  made it within 12 rows of the vice president on Friday, according to a report in Canada's Globe and Mail newspaper.

Canadian Mounties stopped and detained the 48-year-old man, who was reportedly unarmed, and detained him while he was trying to escape.

Canadian authorities are investigating the breach, which took place during the Vancouver Olympics' opening ceremonies.

A Secret Service spokesman told the Globe and Mail that they were expecting further details on the breach from the Canadian Mounties, and that the man was "not in close proximity" to Biden.
