Christmas decorations are being blamed for a fire at a downtown Houston high rise.

The fire broke out around 5:30 a.m. Monday on the fourth floor of Houston Center on Lamar Street and Caroline Street.

When firefighters arrived, they found smoke on the fourth floor, but the building's sprinklers had already extinguished the fire.

The sprinklers did not shut off and ended up flooding the floor.

About an inch of water covered the floor and was draining into the elevator shafts before firefighters were able to shut the sprinklers off.

No one was injured.
