It's been six days and there is still no sign of a missing patient from the Forensic Psychiatric Hospital in Coquitlam.
A Canada-wide warrant has been issued for 58-year-old Kurt Derksen.
Coquitlam Mounties said the patient was out on a pass Thursday at his brother's home in Richmond when he left the house.
Derksen is described as a Caucasian man standing five-feet nine-inches tall with short brown hair and blue eyes.
He has a full beard and is possibly wearing glasses.
Police are asking the public not to approach Derksen, but rather to call 911.
Derksen is the second patient to go missing from the hospital in recent weeks.
Charles Albert Hansen, 60, was reported missing on Nov. 22, but returned to the hospital a couple of days later.
Several patients have gone missing from the hospital this year, but most were returned within a couple of days.
However, one patient who went missing last spring is still at large.
David Fomradas, 34, went missing in May on an unescorted day pass and has not been seen since.
Fomradas is the man behind a bizarre carjacking in 2009 involving Vancouver actress Carly Pope.
His disappearance, along with that of another patient, prompted two reviews of the hospital's unescorted day-pass program and an outcry from politicians and residents in the community.
The hospital also temporarily suspended the program until an internal review was complete.
