The pool and gym at CFB Shearwater in Eastern Passage have been reopened after a threat was made against an individual.

Police blocked the entrance to the military base, located about 15 minutes from downtown Halifax, after reports of someone brandishing a weapon around the gym.

"The Military Police Unit of Halifax received a report of a gunman in the area of 12 Wing Shearwater, around the gym," said Cpl. Joshua John, a military police patrolman.

Seventy people were inside the pool and gym area, including children. They were taken out one by one with their arms in the air. Police said they were taken to another building.

"It may seem excessive I guess but it was just to ensure their safety and ours so that we could ensure everybody wasn't armed, because we didn't get a description," Cpl. John said.

Sub.-Lt. Jamie Tobin, a Canadian Forces spokesperson, said military officials reported the individual is no longer in the area.

He can't confirm if the base was on lockdown because he can't discuss security protocols.

No arrests have been made.
