VIRGINIA BEACH -- High levels of levels of carbon monoxide forced the evacuation of a Walmart in Virginia Beach.
Crews were called to the store on Phoenix Drive around 7:40 a.m. to investigate after a CO detector inside the store went off.
"They are isolating the source, the inspector is also en route," Battalion Chief Amy Valdez told WVEC.com.
Firefighters were checking the store to find the source of the leak. They hope to be able to let everyone back in by noon, but the levels have to be low enough for them to safely return.
No injuries or illnesses have been reported.
