For second time in 12 hours, suspicious object detonated at Indianapolis federal facility

The Minton-Capeheart federal building was evacuated as the Indianapolis police bomb squad detonated a suspicious object Monday June 24.

A woman was in custody Monday after police detonated a suspicious object at a federal building in Indianapolis, only hours after they blew up a suspicious package at a second federal building nearby, authorities told NBC News.

The Minton-Capehart building in downtown Indianapolis houses offices of the IRS, the Department of Homeland Security, the Drug Enforcement Agency and other federal agencies. It was evacuated early Monday afternoon after an object registered a possible hit for explosives as it was being scanned through security X-rays about 2 p.m. (3 p.m. ET), authorities said.

The object was spotted in a woman's bag as it passed through a security X-ray, authorities told NBC News. The woman who brought the object to the building was being questioned by the FBI, NBC station WTHR of Indianapolis reported.

The explosion came about 12 hours after the Indianapolis police bomb squad detonated a backpack at the U.S. Courthouse about four blocks away.

A police dog "hit" on the package about 3 a.m., police said, and it was detonated after nearby hotels were warned.

Police told WTHR that fireworks and marijuana were found in the bag.

Both facilities were cleared and had been reopened by the middle of the afternoon.
