SOUTHBURY, Conn. (AP) Two people have been hospitalized and the residents of five homes displaced in a fire at a Southbury condo complex.

Officials say crews were called to the Heritage Village condominiums at 11:45 p.m. Wednesday night.

The complex is an active senior community and has more than 3,000 residents. The flames damaged five units, which have been deemed uninhabitable.

Firefighters found people outside of the building when they arrived. No one needed to be rescued but officials say about 10 to 15 residents lost their homes.

Authorities say two residents were sent to the hospital in serious condition, one of them after suffering a heart attack. Investigators have not determined the cause of the fire.
