An updated version of the story is below:
Three members of HMCS Winnipeg were detained by Japanese authorities while the ship was on a port visit in Tokyo on Feb. 1.
The crew members, two military members and one civilian employee, were detained for the alleged use of a controlled substance.
One of the military members has since been released by police, while the other two have been charged with use of a controlled substance by the Tokyo Police.
The navy will continue to work with Canadian Consulate officials and Japanese authorities as may be required throughout this process.
The Canadian Armed Forces has a zero-tolerance policy for illicit drug use and possession.
HMCS Winnipeg, which was taking part in Operation Reassurance, is returning to its home port of CFB Esquimalt.
It has already left Toyko and the frigate is expected back in Canada in late February, said an RCN spokesman.
