The roof of a clothing store in evergreen park collapsed, causing customers to evacuate out the back of the building.

It happened Saturday about 1:26 p.m. at the Casual Male clothing store on the 3600 block of West 95th street.

An employee noticed something wrong, and cleared everyone out of the store just as the roof caved in, police said.

No one was injured.

Officials believe structural stress caused the collapse.
