A man was killed by the police after running amok at a restaurant in Columbus, Ohio on Thursday. He stormed inside the establishment wielding a machete and proceeded to attack several people.

"He came through the front door and then started systematically just hitting people with a machete," Karen Bass, a witness to the incident, told WSYX. "I thought it was a personal thing, and then he just started down the row hitting everybody."

The attack happened at around 6 p.m. while the Nazareth Mediterranean restaurant was bursting at the seams with customers having dinner. At least four people were wounded with two reportedly in critical condition. They are being treated in the nearby hospital, ABC News reported. 

The still unidentified attacker is said to have walked into the restaurant earlier and talked briefly with an employee. He left shortly after only to come back with a machete he used to attack people, starting with a man sitting next to the door. People started throwing chairs at the man to drive him away.

He fled the scene using a white car.

When the police apprehended the attacker after a short car chase, he still had the machete in addition to a knife. When he lunged towards the arresting officers with his weapons, he was shot dead, according to FOX News.

Authorities have not released any information about the reason for the attack except to say that it could be nothing but a random act. The FBI, however, was reportedly assisting in the ongoing investigation for still unknown reasons, the Columbus Dispatch reported.
