Eight people were arrested and then released after a dramatic search in the Halifax suburb of Fairview on Saturday morning.
Halifax police said they were executing a search warrant for a gun on Main Avenue and had to call in the Emergency Response Team.
The area was packed with police cars. Neighbours peeked out of the windows to watch the scene and one described it as "scary," reported the CBC’s Anjuli Patil.
Officers seized a replica firearm.
So far there are no charges.
