FORT MYERS, Fla. — Gunfire erupted at a nightclub hosting a swimsuit-themed party for teens in Florida, leaving two dead and at least 17 wounded, officials said today.

It was not immediately clear what triggered the violence. Fort Myers police detained three people and said the area around Club Blu had been deemed safe, police Capt. Jim Mulligan said in a statement.

“While we are still learning the details about what happened this morning, we know that some of the victims of this terrible incident were children,” Gov. Rick Scott said in a statement. “We will continue to pray for the victims and their families.”

Three people remained hospitalized this morning, Cheryl Garn, a spokeswoman for Lee Memorial Health System, said in an email. All others were treated and released. Two people brought to two other area hospitals were also treated and released, Garn said.

Ages of the patients ranged from 12 to 27, Garn said.

The club is in a strip mall that includes a daycare center and is across the street from a large apartment complex. Officers had the area taped off as crime scene technicians scoured the strip mall parking lot for clues.

State records online show the alcohol license for Club Blu was revoked on June 7. The records from the Department of Business and Professional Regulation say the license was revoked because of an incident that occurred a year ago, but there are no additional details available. The same records also show that a complaint was filed in 2014 for “criminal activity” and that the club was given an official notice.

The violence at Club Blu erupted about 12:30 a.m. today, Mulligan said. There were two active crime scenes, police said. Several hours later a street in the area remained closed as police investigated.

In a statement, authorities said the Fort Myers police and the Lee County Sheriff’s Office were “actively canvassing the area looking for other persons who may be involved in this incident.”
