PITTSBURGH (KDKA) — Pittsburgh Police are investigating two explosions and searching for the driver who allegedly threw an explosive device out of a moving truck on Sunday night.

“I was sitting on my couch watching TV and heard a loud boom outside. It sounded like it was right out front,” said Lawrenceville resident Jared Rackley.

That loud boom was captured on Jared Rackley’s Nest Doorbell, and so was a white pickup truck.

“The truck actually showed up within 30 seconds after the explosion and matched the pictures they had put on Twitter earlier,” said Rackley.

The pictures Rackley is talking about are images Pittsburgh Police shared showing a white two-tone older model pickup truck. It’s the truck police believe the IED was thrown out of as it was traveling down Penn Avenue.

The incident happened on Penn Avenue in Lawrenceville just after 9 p.m. Sunday.

Police and firefighters were called out for reports of an explosive device that was thrown from a moving vehicle.

“The house shook, sort of inside the core. It was so loud. The whole neighborhood shook,” said Lawrenceville resident Catherine Shea.

Resident Tom Shannon said, “We thought it was a transformer that went off last night.”

“If somebody happened to be walking by here last night they could’ve gotten injured,” said Shannon.

Penn Avenue was closed between 35th and 40th Street while investigators were processing the scene.

“We walk our dog along here everyday. There’s lots of kids in the neighborhood. Just a little too close for comfort,” said Shea.

Police are also investigating possible reports of an explosion in the 200 block of Dinwiddie Street in the Hill District just after 10:30 p.m. Sunday. They said later Monday that this incident was not related to the one in Lawrenceville.

According to police, residents there reported feeling their homes shake and some type of odor in the air, but the Bomb Squad with its explosive sniffing K9s didn’t recover any evidence.

Two separate bomb squads are investigating these incidents. The FBI is also helping with the investigation.
