WARRINGTON, Pa. (CBS) — A 50-year-old man was in custody in Bucks County this morning, the result of a manhunt that began after his mother found several pipe bombs in the home they share.

It all started Wednesday evening, when the 70-year-old woman returned home from vacation to her home in the 1800 block of Saddle Drive in Warrington.  Police say she found an explosive device on her kitchen table.

She shares the home with her 50-year-old son, who wasn’t around, so she called 911.

Warrington Police responded with the bomb squad and agents from the federal Bureau of Alcohol, Tobacco, and Firearms (ATF), and found two other devices in the home.

Around a dozen surrounding homes were evacuated while those devices were defused (see previous story). About two hours later, neighbors were finally given the all-clear.

“In one sense you feel kind of relieved because no one was hurt, but in another sense, because I live 100 feet from the house, that’s kind of nerve-wracking,” said one.

Police took bags of evidence and several firearms out of the home.

Police were looking for John Grzyminski, whom they say was last seen in a black Dodge pickup truck with a chrome “#8 Dale Earnhardt Jr.” license plate on the front.  He was traveling with two small dogs and police say he likes to frequent parks and wooded areas.

In addition to the bombs, police also removed several firearms, but police said he might have a .357 with him in his truck. They asked anyone who saw him to call 911 instead of approaching him.

The manhunt ended when Grzyminski’s truck was spotted in Solebury Township, near New Hope, shortly before noon today and he was taken into custody.
