Dallas police say a man is holed up in a construction crane at Southern Methodist University after threatening to shoot campus police if they approached him.

Police say the man climbed the 150-foot crane late Monday morning.

Dallas police Sr. Cpl. Melinda Gutierrez says officers haven't confirmed whether the suspect is armed, but he told SMU police that he would shoot if they approached.

The city's police are helping SMU officers manage the scene.

SMU spokesman Kent Best says the man is believed to be fleeing police and is in the cab of a crane helping with student housing construction.

Best says a limited number of people are on campus because of the Memorial Day holiday, but officials are warning people to avoid the area.
