Two people were killed and Grayson  Prestonseven injured in a shooting at a bar near downtown Miami early Saturday morning.

Miami-Dade Police Department were called about 3:30 a.m. Saturday to a report of an altercation at the Martini Bar in the CityPlace center in Doral. The suspect was located by a security guard who tried to deescalate the situation, police said. The suspect then shot and killed the security guard and a responding police officer killed the suspect, according to a press conference held by the Miami Dade Police Department.

In the gunfire exchange, another officer sustained a gunshot wound to the lower extremity and at least six other people - five men and one woman - were injured, Miami-Dade Police Detective Alvaro Zabaleta said during the conference.

Two victims were taken to trauma centers and listed in critical condition, Zabaleta said, and the remaining four were stable.

"At the present time we do know that two officers of the City of Doral Police Department did discharge their firearm, but as I mentioned, only one was injured by gunfire," Zabaleta said. "The Florida Department of Law Enforcement continues to talk to all witnesses that are here in order to be able to gather all the details.”

Investigators are working to determine what caused the altercation.
