Police shot and killed a man who injured four people apparently at random in an Ohio restaurant last night after the suspect fled the scene.

Witnesses at the Mediterranean restaurant in northeast Columbus gave a great description of the white getaway car and even took video that provided partial information on the license plate, Columbus police spokesman Sgt. Rich Weiner said.

An officer working special duty nearby at the large Easton Town Center shopping complex spotted the vehicle, and officers confronted the man, who got out of the car holding a machete in one hand and a knife in the other, Weiner said. Police tried unsuccessfully to use a stun gun on him, then shot him when he lunged at them, he said. No officers were hurt.

The Associated Press reports that the attacker’s motive is still unclear. Police said the man walked into the restaurant, left after a conversation with an employee, then returned about a half hour later and starting attacking two people sitting in a booth at the front of the eatery.

Police said employees and patrons tried to stop the man, with some throwing chairs at him and one having a physical confrontation with the attacker before he fled.

CBS News has more information, reporting “that investigators have identified the suspected attacker as Mohammad Barry. CBS News homeland security correspondent Jeff Pegues reports that investigators were running down leads to try to determine if the attack was somehow tied to terrorist organizations.”

Pegues reports the suspected attacker has a Somali background, and officials believe he may have traveled to Dubai in the United Arab Emirates in 2012. Pegues reports that law enforcement is concerned that this incident has the hallmarks of the type of so-called “lone wolf” terrorist attack that they have been working to stop.

Police said employees and patrons tried to get the man to stop.

“Some of the patrons there started throwing chairs at him just trying to get him out of there,” Weiner said.

The local NBC affiliate reports that the FBI is assisting police in their investigation. FBI agents were seen at a northeast Columbus apartment removing bins of evidence from one of the units.
