At least three people died and four others were wounded after a shooting at a Columbus nightclub on Wednesday night, NBC 4 reported.

The shooting took place shortly after 10 p.m. at Alrosa Villa, located at 5055 Sinclair Road.

Two members of the heavy metal band Damageplan were shot and killed, including Dimebag Darrell, formerly with the band Pantera, NBC 4's David Wayne reported. Another band member is reported as dead but it is unknown which member. The alleged gunman also died at the scene, Wayne reported.

Shortly after the band began playing its first song, a man reportedly ran onto the stage and began shooting, according to a witness who identified himself as Sean. Some members of the audience reportedly thought the man running onto the stage with a gun was part of the band's act, NBC 4's Erin Tate reported.

Witnesses said that several shots were fired at the band. Witnesses said that a bouncer at the club tackled the alleged gunman before that person was shot and killed. It was unclear as to whom shot the alleged gunman.

Alrosa Villa is a popular north Columbus nightspot for young adults, featuring rock and heavy metal bands, NBC 4 reported.

According to the band's Web site, Damageplan was touring nationally. It performed in Buffalo, N.Y., on Tuesday night and had a concert scheduled in Flint, Mich., on Thursday.

Damageplan featured former Pantera artists Dimebag Darrell and Vinnie Paul. The pair were joined by vocalist Patrick Lachman and bassist Bobzilla.

COLUMBUS, Ohio - A man walked onstage in a crowded nightclub during a rock concert Wednesday night and opened fire, killing at least four people and wounding at least two others before he was shot to death by police, authorities said.

Members of the heavy metal band Damageplan had just begun their first song at the Alrosa Villa when the man opened fire on the band, initially shooting the guitarist, who went by the name "Dimebag Darrel," a witness said. According to the band's Web site, the guitarist and another member are formerly of the heavy metal band Pantera.

The witness, 22-year-old Chris Couch, said he was standing about 30 feet away from the stage when he noticed a man wearing a hooded sweatshirt and hockey jersey walk up to the stage, followed by a bouncer and another club employee.

The man in the jersey climbed onto the stage, started yelling and shot the guitarist five or six times at close range, Couch said. Couch said the gunman also shot a bouncer who pulled him off the musician.

Columbus police spokesman Sgt. Brent Mull said a police officer shot and killed the gunman. It wasn't immediately clear whether the officer was already at the show or had responded to an emergency call. Authorities didn't immediately provide the identities of the victims.

After the shooting began, Couch and a friend headed for the exit along with a tide of hundreds of fans.

"It was definitely a grudge. It was against something," Couch said.

Amanda Stankus, 19, who attended the show with Couch, said she initially thought the shooting was part of the show.

"I just saw the guitarist fall down, and we decided to get out of there," said Stankus.
