A man strapped with "tactical weapons", sporting body armor and carrying 100 rounds of ammunition has been arrested at a Missouri Walmart just days after another heavily-armed man killed 22 people at a Walmart in Texas.
No injuries were reported and no shots were fired.
An off-duty firefighter held the man at gunpoint until officers arrived.
KY3 in Springfield reports that the Springfield Police Deprtment responded to an active shooter call at the Walmart at Republic Road on Thursday evening.
He was arrested after walking out of the store with his weapon, police said.
Lucas said that the suspect had more than 100 rounds of ammo with him.
According to Lucas, a 20 year old put on body armor in the parking lot, then walked inside with a tactical rifle around his neck and a handgun on his side.
"His intent was not to cause peace or comfort... So he certainly had the capability the potential to harm people", Lucas said.
Security video and the man's social media profiles would be reviewed to try to learn the man's motive and whether he meant to shoot anyone, he said.
It was a "really scary, unsafe situation", police at the scene told media, adding that they would investigate the man's social media accounts to try to determine if a threat was intended. "In fact, he's lucky to be alive still to be honest", Lucas also said, according to multiple local news outlets.
The incident comes after a white supremacist terrorist massacred almost two dozen people in a domestic terror attack at a Walmart in El Paso last Saturday in which the terrorist targeted Latinos.
