Halifax police search home where deck collapsed, injuring 6

Halifax Regional Police have executed a search warrant at a home where a deck collapsed and fell three storeys onto another deck, injuring six people.

Police say they searched the small apartment building "to allow further processing of the scene."

Once the search was over, tenants were allowed to return home. 

Police say the investigation into the deck collapse continues and involves other municipal officials.

Police say seven people were on the deck of a house on Brussels Street during a party early Saturday morning when the deck collapsed, landing on another deck below. Police have not said how many people were on the lower level.

Four women and two men, all in their early 20s, were taken to hospital. Police say some of the victims have serious injuries but all are expected to survive. 

Home's 2002 addition controversial

A newspaper clipping from 2002 shows the deck was part of a controversial addition to the original home. 

​According to court documents and an article by the now defunct Halifax Daily News, there was backlash from neighbours when the owner at the time attempted to turn the house into two apartments

The issue went to court and the owner was ordered to pay thousands of dollars to the city. 

Last September, 15 people were sent to hospital after a deck collapsed in Dartmouth.
