LAS VEGAS (AP) — Las Vegas police are investigating an armed robbery at a Walmart.

Authorities are looking for four armed men who they say wore masks during a takeover-style robbery Monday morning.

According to police, the four men arrived at the store in a light-colored, newer-model sedan, ordered everyone to the floor and demanded money from employees. It is unknown how much money the men stole.

The suspects fled through the front doors to their awaiting car and left before police arrived.

No one was injured in the incident.
