The suspect was taken into custody by Springfield police after he allegedly entered a local Walmart at around 4:10 p.m. while armed and dressed in what appeared to be tactical gear.

He reportedly grabbed a shopping cart and began pushing it around while recording himself on a phone, Springfield’s KYTV reported. After being alerted to this, the store manager pulled a fire alarm and shoppers fled.

Reports said that Andreychenko was armed with a loaded gun and more than 100 rounds of ammunition.

Springfield police Lt. Mike Lucas told KYTV that the suspect’s intent was “to cause chaos.”

"He certainly had the capability and the potential to harm people. And then what has happened in Texas and Dayton and all that kind of stuff the last seven days, that is on everybody's mind," he added

It wasn't immediately clear if Andreychenko told cops why he was at the store, however, the incident comes five days after a mass shooting at a Walmart store in El Paso, Texas, that resulted in 22 deaths.
