(CNN)Two people are dead and at least 14 others injured after a shooting at a Fort Myers, Florida, nightclub, according to Capt. Jim Mulligan of the Fort Myers police.

The shooting took place in the parking lot of Club Blu Bar and Grill, according to CNN affiliate WINK-TV. The call alerting police to the shooting was received at 12.30 a.m. Monday.

Police didn't say how many shots were fired, but at least 36 yellow evidence markers were placed around the front of the establishment.

Police said they have detained three adults in relation to the shooting.

Injuries ranged from minor to life-threatening. All the injured were transported from the scene by Lee County Emergency Medical Services to area hospitals.

Lee Memorial Hospital said in a statement it had received 16 people ranging in age from 12 to 27. One died at the hospital.

Police are working to identify the deceased.A flier posted on Facebook advertised a "Swimsuit Glow Party" at the club Sunday night. It said no identification would be required to enter, meaning the party was open to all ages.

Investigators and crime scene personnel are trying to determine what happened.

Police are investigating two other related scenes, one on Ortiz Avenue, where a person of interest has been detained. The other scene is on Parkway Street.The area is "deemed safe at this time," a police statement said, but Evans Avenue, between Carrell Road and Winkler Avenue, has been closed, and motorists were told to take alternate routes.

Gunshots at the Parkway Street scene hit property, and a bullet grazed one person, according to WINK.

An all-out search for those involved is underway, police said.

The Lee County Sheriff's Office stopped a vehicle that had a suspect in it, Mulligan added, but did not give any additional detail about the stop.
