An overnight fire has claimed the life of a Chester County resident.

A North Coventry police officer on foot patrol noticed flames coming from a house in the 100 block of Mount Zion Ave. just before 4 a.m. Multiple fire companies arrived and extinguished the blaze at the single family home quickly, said Police Chief Robert Schurr.

Police are not releasing details about the victim pending notification of next of kin, Schurr said.

Most of the damage to the home was caused by smoke and heat, Schurr said. The cause of the fire is under investigation.
