Channel 8 Eyewitness News spoke with a customer inside Chick–fil–A who got involved with the suspect.

Todd Ogden says he tried to tackle Joseph F. Cimino when he started acting out and threatening people.

"I tried to basically just try and take away his arms from swiping at people and he is a pretty big guy and I clearly have a weak upper body so I could not take him down," Ogden said. "My goal was to drag him out of the place and just tell him that families are here and lets just take this altercation outside."

Ogden is the president of the Downtown Lincoln Association. He was in the restaurant with his wife when the chaos unfolded.

He says the man was out of control and he had no idea it would escalate to the level it did.

When the car crashed into the restaurant, the goal was to get everyone outside of the building.

"My wife, she is a social worker and she did an amazing job of getting people and helping people get out of the building and trying to figure out what the situation was occurring and really just trying to figure out and assess the situation and try to get as many people out as safe as possible," Ogden said.

Ogden says this is an incident that could happen anywhere. Moving forward, he urges people to treat others how you would like to be treated and be patient.
