The Montgomery County bomb squad used a robot to handle the suspicious items.
Police say they used a water cannon to blow up two of the devices found. They have proven not to be dangerous. The bomb itself has been neutralized.
Several area buildings, including the nearby YMCA, were evacuated.
West Chester Police Chief Scott Bohn described the suspected bomb as having, "some wiring, there is some sort of a circuit or a piece of electronics. There is a container of fluid and a metal pipe."
The FBI, the ATF, and state and local officials are investigating, looking for the person who planted the bomb.
Sources tell Action News that this does not appear to be the work of the so-called "suburban bomber" who struck repeatedly back in 2000, however the investigation cotinues.
Police urge anyone who sees any suspicious devices or packages to call 911.
