A shooting erupted inside a nightclub packed with hundreds of people in the city's tourist district early Sunday, killing two people and injuring 10 others, authorities said.
It was the second mass shooting at a Florida nightclub this weekend.
The shooting took place just before 1 a.m. with about 300 people inside the Glitz Ultra Lounge. Three off-duty Orlando Police Department officers were working security at the club when the shooting started, the Orlando Sentinel reported (http://bit.ly/1mlKHAt).
Police spokeswoman Michelle Guido said it's not clear what prompted the shooting or if any of the off-duty officers fired their weapons.
As many as three shooters are being sought.
One person was shot and killed inside the club, police said. Nine were taken to a hospital with gunshot wounds. Of those, one died at the hospital, one is in critical condition and the rest are being treated for injuries that were not life-threatening. Two others — including one with a gunshot wound — were seen at another hospital.
In addition to the off-duty officers, the club has its own security, police said. Detectives are reviewing security video from the club in hopes of gleaning clues.
In Tampa, eight people were shot at a strip club Saturday. A 21-year-old man died. No arrests have been made in that case.
