A northwestern Indiana man has been arrested on federal charges in connection with a pipe bomb that exploded last month at a post office.

U.S. Attorney Thomas Kirsch II announced Thursday that 45-year-old that Eric P. Krieg of Munster, Indiana, was charged with knowing possession of a destructive device and transporting explosive materials. Kirsch says a complaint alleges Krieg mailed a package at the East Chicago post office that exploded and that he mailed a suspicious package to another individual on Sept. 29.

Kirsch says search warrants were executed Thursday on Krieg's residence, place of employment and vehicle.

A postal worker suffered minor injuries in the explosion.

It wasn't immediately clear if Krieg has an attorney.

The federal prosecutor in northwestern Indiana is planning to release more information on a pipe bomb that exploded last month at a post office.

The office of U.S. Attorney Thomas Kirsch II says he'll hold a news conference Thursday afternoon to provide an update into the Sept. 6 explosion in East Chicago. A postal worker suffered minor injuries in the explosion.

The FBI two weeks ago released a sketch and description of a person of interest in the case.

The mayor of neighboring Hammond, Thomas McDermott Jr., said last week that the pipe bomb was believed to have been intended for a city contractor. He said a city worker received a bulky package containing threats in a separate incident. McDermott said he had spoken to the FBI about the threats.
