An Omaha man is facing charges of possessing what's described as a pipe bomb. Investigators are looking for his brother, Jonathan, too.

On Tuesday, 27-year old Matthew Rufle was been booked into the Douglas County Jail. He's accused of having a pipe bomb and the materials to make more from a home he shared with his brother on 57th & Potter Street.

Omaha Housing Inspectors placed a danger sign on the window explaining that the home is unfit for people or animals.

Omaha Police initially received a 911 call from Jonathan Rufle's girlfriend saying she was assaulted by him. She lived there too and gave investigators permission to search the home.

When investigators entered on Tuesday -- officers, in plain view, say they saw drug paraphernalia, along with explosive materials and destructive devices. "It bothered me," says neighbor Chris Steele, "After all, if you have someone building pipe bombs next door to you, you want to know why and where is he going to use them."

Matthew Rufle, who has 52 criminal entries in the Omaha Police database, had a syringe and two knives in his pants pocket according to the OPD incident report. The Nebraska Humane Society removed a female dog from the home.

Just this summer, the Benson View Acres neighborhood got together and formed a neighborhood watch program as a way to keep neighbors involved and to watch out for each other - mostly due to this one home.
