Chattanooga, Tennessee.

A gunperson began firing at a group of people outside of the Dream nightclub when its security guard jumped into action.

Head of security Joe Reed thinks the attack was planned, revealing security footage of the 24-year-old suspect parking his car down the road before attacking.

"It was quick action by our licensed security guard who did what he had to do to protect innocent lives," said Reed.

The suspect was injured with non-life-threatening injuries.
