(CNN) -- In a daring, movie-worthy operation, three men escaped from a Canadian jail by helicopter, prompting a massive manhunt, local media reported.
The men escaped from a detention center in Quebec City using a green helicopter Saturday night, CNN partner CBC reported. It's unclear how they pulled it off -- authorities are still working to get more details.
"We are talking closely with the detention center to figure out exactly how the escape transpired," Ann Mathieu, a spokeswoman for Quebec Provincial Police, told CBC. "The priority number one is to find the helicopter."
A manhunt is under way for Yves Denis Yvon Lamontagne, 35, Denis Lefebvre, 53, and Serge Pomerleau, 49.
The first two were arrested on drug charges in 2010 and were awaiting trial, according to CBC, which did not provide information on the third suspect.
This is the second brazen jail escape in Canada in a little over a year.
In March 2013, two men posing as tourists commandeered a helicopter from a Canadian tour company, ordered the pilot to fly over a detention center near Montreal, hoisted two inmates into the hovering aircraft using cables -- and zipped away.
It was a real "James Bond moment," witness Francis Emond said about last year's escape from the facility in Saint -Jerome, northwest of Montreal.
