Jones was flown to Carolinas Medical Center in Charlotte, where she was treated and released.

The shooting comes three days after a teen fired a .38-caliber revolver into a door at Club Le'Brea, another Chester nightclub. A 19-year-old Chester man was shot once in the head.

Five youths, including a 14-year-old, were taken into custody Saturday in the Club Le'Brea shooting, which left Mario Hughes with a bullet lodged near his temple.

Club Le'Brea and the 321 Sportsbar are known to officers who respond often to both clubs for shootings and fights, Chester County Sheriff Robby Benson said.

Authorities have not made any arrests in the New Year's Eve case. However, police are looking at a handful of suspects and may file charges before the weekend, Darby said.

Around 11:30 p.m. on New Year's Eve, police responded to Chester Regional Medical Center for a shooting that happened at the 321 Sportsbar at 560 Columbia Road, Darby said.

"She stated that she had just sat down on a couch at the bar when she was struck," Darby said. "Somebody fired shots into the club."

It is unclear how many people were in the club during the shooting, officials said. Police recovered six bullet casings.

A familiar problem

Chester County authorities have responded at least 14 times to the 321 Sportsbar for shootings and fights, said Benson, who could not provide a number of similar incidents at Club Le'Brea.

Police have not determined a motive in either shooting, and neither incident is related, Benson said.

Still, officials plan to step up security for weekend club gatherings.

"We're going to do all we can do, but we need help from the people who go to these clubs," Darby said. "They need to pick up the telephone and dial 911 when they know something like this is going to happen or a fight is about to take place."

Instead, he said, police do not receive much cooperation from potential witnesses.

"I'm not saying tell on people, but we need help," Darby said. "We need people to come forward and tell us what happened."
