A surveillance video of a gangster's daring escape from one of B.C.'s maximum security jails is raising questions about security in B.C. prisons.

Prison guard Edwin Ticne can be seen leading gangster Omid Tahvili -- disguised as a cleaner -- through several locked doors right out of the North Fraser Pre-Trial Centre.

Having one prison guard help you out shouldn't be enough, suggested security expert Leo Knight.

"He should not be alone and there should be somebody else who has to engage and disengage that lock," Knight said, pointing to one of the doors that Ticne led Tahvili through.

"That should be obvious to the other guards, who are monitoring cameras," said Knight.

Tahvili was facing charges including kidnapping, unlawful confinement, assault with a weapon, sexual assault, threatening and use of an imitation gun in connection with the kidnapping of a Surrey man in his own car on June 20, 2005.

He walked out of the prison in November, and Ticne was arrested for his role in the prison break shortly after.

Last week, Ticne pled guilty to helping Tahvili escape, and admitted he was promised $50,000 for his efforts.

One minute of a two-hour video was provided to CTV News by B.C. Corrections after CTV requested its release.

The doors are remotely controlled from a security checkpoint. Someone was watching that video and let them both out.

It's not clear whether Ticne had help from other guards. B.C. Corrections say no one else is being investigated. An internal review has been done, but it remains secret.
