Suspicious device detonated in Round Rock neighborhood

UPDATE 2:40 p.m.: At a press conference, Williamson County Sheriff Robert Chody said that deputies were investigating the home after a property manager reported finding suspicious materials, including a bomb-making manual and ammunition, while cleaning up after a tenant.

The homeowner reported the materials on Saturday, and deputies were searching the home with a K-9 unit Monday afternoon when they witnessed a pipe that appeared to be a pipe bomb in the home, Chody said. Deputies immediately backed out of the house and alerted the Austin Police Department Bomb Squad.

No explosive was found inside of the pipe, Chody said, but officials performed a controlled detonation as a precaution.

A secondary search of the residence is currently underway.

"We have nothing to show that the public is at risk, but I do want to remind the public that it was an incendiary-looking device. I don't want to put anybody at alarm, but at the same time, I think we have a responsibility— especially in the Austin area after what we went through some months ago—that you need to pay attention around your neighborhoods," Chody said. "If you see something, report it."

Chody said that a suspect has not been identified and the Williamson County Sheriff's Office is working with the FBI to determine if charges will be pressed in the incident.

UPDATE 2:05 p.m.: Chody tweeted that a noise in the area was a controlled detonation.
