(Hopkinsville) - An armed robbery at AC Automotive Monday had three suspects shooting at police while another was driving the getaway car.

So far, only Marshall Brown, 23 of Hopkinsville has been arrested after admitting he was the driver of the getaway car stopped by Oak Grove Police on I-24 near the Tennessee state line Monday evening. One of the four suspects allegedly shot at the arresting officer then fled on foot to a nearby wooded area.

Two men at AC Automotive were assaulted in the armed robbery. One of the victims positively identified the driver of the getaway car and another was reportedly pistol-whipped as the robbers got away with several cell phones and some cash.

K-9 units and a police helicopter from Nashville were engaged in a massive manhunt Monday night but so far, the three remaining suspects are still at-large as of this morning.

Oak Grove and Hopkinsville Police have not yet released a description of the three at-large suspects.
