ATF: Arsonist Targeting Center City Apartment Complex

PHILADELPHIA (CBS) -- The Bureau of Alcohol, Tobacco, Firearms and Explosives is investigating a string of suspicious fires in a Center City apartment complex.

The ATF says there has been a total of six small fires that were intentionally set in the hallways and trash rooms at the Sterling Apartment Homes at 1815 John F. Kennedy Blvd.

"I have been in this business a long time. Let me tell you something, it is very concerning to me," said ATF Special Agent Sam Rabadi.

Each happened on different floors of the building, in common areas. Each were small fires, quickly put out by sprinkler systems.

The first incident occurred on July 13 and the last incident happened Aug. 3 around midnight.

For most of the roughly 1,000 residents that live here the frequent fire alarms have been a headache to deal with.

For eight  people though, they've had significant water damage to their apartments. At least two of them have had to be relocated.

The ATF and the building management have put a $10,000 reward for anyone with information leading to an arrest of the arsonist here.
