(BERKELEY) Live explosives were found in a home Monday in west suburban Berkeley, authorities said.

Crews from Berkeley and the Cook County Sheriff’s Bomb Disposal Unit responded to a Berkeley home sometime before 8 p.m. and found what they believed to be homemade explosives, officials said.

The explosives were later determined to be real, officials said.

Crews were given permission to take the devices to the Elmhurst Stone Quarry in DuPage County, where they were destroyed safely in two separate detonations, according to the village of Elmhurst.

Berkeley officials could not immediately be reached Tuesday to provide further details.
