Suspect in custody in connection with pallet fire at Walmart

Police in Thornton have a suspect in custody in connection to a pallet fire that happened Monday morning. The fire broke out just before 9 a.m. at the Walmart store located at 9901 Grant St. 

Several pallets and cardboard boxes were burning which caused a lot of smoke. That smoke billowed onto Interstate 25 which forced a lane closure for a short period of time. 

The fire was quickly extinguished with no injuries. 

The suspect has not been identified.
