Firefighters work to douse hot spots after a large brush fire in Allentown early Wednesday morning.
The fire broke out on a wooded hillside above Constitution Drive around 3:30 a.m.
Five homes and an apartment building on nearby Skyline Drive were evacuated as a precaution according to Captain John Christopher of the Allentown Fire Department.
Christopher tells NBC10 the fire went to three alarms and was tough to fight because of the steep terrain and limited water supply in the area.
The fire was declared under control around 5:30 a.m. and the evacuees were allowed to return home.
Firefighters continued to comb the woods with water packs on their backs, searching for hot spots.
There were no injuries or property damage, according to Christopher. The cause of the fire is under investigation.
