IRVING (CBSDFW.COM) – Winds gusting up to 40 miles an hour fanned flames from a massive fire that destroyed a portion of an Irving apartment complex.

Heavy flames and smoke were already showing at The Crossings on Walnut Hill when firefighters arrived just before midnight Thursday.

A second alarm was quickly called and eventually a third and fourth.

Firefighters from other cities, including Dallas, helped fill in at various Irving fire stations while crews from that city worked to contain the flames.

Many living at the complex said they were jarred awake by pounding on their doors and cries of ‘fire.’ One apartment resident said, “It’s pretty scary. Thank God they woke us up because otherwise we would have been gone.”

There were no injuries, but 32 people were left homeless, officials said.

The Red Cross was called out to assist those displaced.

Investigators were working to determine what caused the fire.
