A wheelchair-bound Calgary man was seriously assaulted and sent to hospital in a northwest Calgary home invasion early Thursday, police said in a release.

While the home in the 100 block of Citadel Peak Circle N.W. may have been targeted due to a small medical marijuana grow operation, Calgary police say the occupants are not known to police or to have ties to organized crime.

Police say an armed group broke into the home at about 3:40 a.m. and tied up two male residents, seriously assaulting one of them, a man in wheelchair. He was taken to hospital in stable condition. The other resident was treated on scene and released, police said.

The group stole items from the home and left.

At around 2 p.m. police made a traffic stop in the 2800 block of 10th Street N.W. finding two men they believe were involved in the home invasion, along with a pistol with a prohibited high capacity magazine and a small amount of weed.

Police then executed a search warrant at a condo in the 800 block of 4 Avenue S.W. where evidence linked another four people to the invasion.

Six people are facing multiple firearm, possession, break and enter to commit robbery and other charges:

24-year-old from Calgary

24-year-old from Sherwood Park, Alta.

20-year-old from Grande Prairie, Alta.

22-year-old from Grande Prairie, Alta.

27-year-old from Burnaby, B.C.

26-year-old from New Westminister, B.C.

All of the accused are scheduled for court appearances Monday.
