(KMOV) -- Emergency crews left scene of a partial building collapse in south St. Louis just a little more than an hour after it happened.
It happened around 5:00 a.m. on Tuesday in the 3600 block of South Grand.
No one was injured in the collapse.
A check-cashing business and a restaurant are on the ground floor of the building. On the second level are about 20 apartment units.
News 4 talked to the building owner, Karen Karabell who says the building's been around since the 1920s. She heard from one of her tennants shortly after 5:00 a.m. and rushed over.
Some on the scene believe that water on the roof and strong winds played a roll in knocking off part of the top of the building. Bricks, cement, a few window air conditioning units and an awning cover the sidewalk outside the building.
Karabell says she has photos of what the top of the building looks like and says she plans to eventually restore it.
At this point the apartments in the building remain occupied.
A private company will be called upon to clean-up the mess and remove bricks and other pieces hanging off the roof. With the gusty winds it's still a dangerous place to be as of 7:30 a.m. and yellow tape surrounds the area so people stay out of the way.
