The security guard determined the man’s identification didn’t look legitimate and told him to leave. Instead, the driver accelerated and drove through the gate. Military police pursued him until he fled the base, and police from nearby St. Robert chased him toward Rolla about 50 km away. St. Robert police chief Curtis Curenton says his officers were fired on with what appeared to be an AK-47 machine gun during the pursuit. The man was later spotted on the Rolla campus of Missouri University of Science and Technology, but left without any firing any shots, police said. The campus was on lockdown.
