A four-alarm blaze at the 1600 Church Road Condominiums in the Wyncote section of Cheltenham Township has injured five residents and two firefighters. They were treated at Abington Hospital. About 100 residents of the three-story building on Route 73 are without a place to live because their units were damaged. Fire officials have evacuated the entire complex so an additional 100 residents have been displaced. The Red Cross has set up a temporary shelter at the nearby high school. The cause of the fire remains under investigation.
