One of the 76 men aboard a cargo ship that was seized off Vancouver Island last week has been ordered released from detention, but 75 others will remain in jail.

The Immigration and Refugee Board wrapped up 48-hour detention hearings for all 76 of the men late Friday.

No details are being given about the one person who was granted an order for release with terms and conditions, but there is at least one minor among the would-be migrants.

With the 48-hour detention review hearings now complete, seven-day detention reviews will begin on Monday.

The men are being held at a jail in Maple Ridge, B.C., east of Vancouver.

Tamil officials in Canada say the men were fleeing persecution in Sri Lanka after a long civil war.

Federal Immigration Minister Jason Kenney has said the RCMP are investigating the migrants to determine if any of them have connections to terrorist or criminal organizations.
