In a separate incident at a nearby Best Buy in Maplewood, the Maplewood Police Department said a "large group" of 10-12 adult and juvenile suspects entered the store together and stole multiple high-value items.

Police called the incident a "grab and run" theft, adding that televisions, tablets and hoverboards were among the items stolen.

When police arrived, the suspects were already gone.

Police were looking into whether the two incidents were connected.
