“Me and him ride bikes a lot and he comes in my alleyway and we play football and basketball,” Wright said.

Wright says he dropped Jeremiah off at his home minutes before the blast.

“We were coming around the block and we see him go into his house and when we went down there and about to turn we heard a big boom,” Wright said.

Fire crews were first called to Washington Street and Butler Avenue in Pottstown around 8 p.m. Thursday. When they got to the scene, they found a house had exploded, which caused a two-alarm fire and multiple people needed medical attention.

The Red Cross is helping displaced families.

Pottstown schools were closed Friday.
