LINCOLN, Neb. (AP) — A homemade explosive device has been found on a Lincoln elementary school playground.

A fire investigator seized the small explosive Tuesday afternoon and removed the device from Brownell Elementary School.

Lincoln Fire Investigator Ken Hilger says bomb squad members were called to the school just before 1:30 p.m. after a staff member found the item.

A black canister with a wick was taken inside a school office and that’s when authorities were called. Staff then evacuated the office.

Officials say the wick appeared to have already been lit and burned itself out. The device didn’t appear to have exploded.

Hilger says the device wasn’t very big but was capable of hurting someone.
