SELKIRK, Man - There will be more guards, but no fence at a Winnipeg-area mental health facility where bus beheader Vince Li has been granted escorted walks.

Li is being held at the Selkirk Mental Health Centre after being found not criminally responsible for stabbing and beheading Tim McLean on a Greyhound bus in July 2008.

The Criminal Code Review Board, which examines Li's care every year, decided this spring that he should be allowed walks with two staff members on the unfenced grounds.

The Manitoba government says in a release that two more full-time security officers have been hired and will be dedicated to escorting forensic patients.

It says the walks will take place only during peak staff periods and will not occur until all risks have been assessed and security measures are in place.

The government release, which does not name Li specifically, says it will take about two months to get all the security arrangements implemented.
