OMAHA, Neb. (AP) — Police say five men broke into an Omaha school and robbed a teacher who was working in her classroom.

The Omaha Police Department says the men entered the Integrated Learning Center about 5:30 p.m. Sunday. The group took several items in the school before two men broke off and entered a classroom where the 65-year-old teacher was working.

The teacher tells police that one man threatened her with a hammer. Police say the pair then took her purse, cellphone, car keys and her Honda Fit.

Police say the men likely broke a window on the north side of the building to get inside. No arrests have been made. The case remains under investigation.
