An NFL defensive back with a history of legal problems is being investigated after reports of an early-morning incident involving a physical fight and at least one shot being fired at a Texas club. Denver Broncos cornerback Aqib Talib and his brother are being investigated for aggravated assault after an altercation at a Dallas-area nightclub on Wednesday morning, according to reports. During a 2011 incident involving two guns when he playing for the Tampa Bay Buccaneers, Talib and his mother were accused of shooting a gun at his sister's live-in boyfriend in Garland, Texas. Denver Broncos cornerback Aqib Talib and his brother Yaqub are being investigated for aggravated assault . Talib was in trouble before and was wanted on charges of aggravated assault with a deadly weapon in 2011 . During the latest incident, a shot was fired outside of Club Luxx in Dallas, Texas, after a physical fight inside . During the incident on Wednesday, Talib and his brother Yaqub had a physical altercation with someone inside Club Luxx and then a shot was fired outside around 2am, WFAA reported. When Dallas officers responded to the active shooter call, the man who called police said three black men had been involved in a disturbance and one of them had tried to punch him. The man also said one of the men pulled out a gun and aimed it at him before firing a round off into the sky outside the bar and causing 'an immediate panic'. The Talibs left the area in a Range Rover and a Jaguar and went to the XTC Cabaret. Police found the brothers at the second club and impounded the vehicles to look for evidence. The brothers were both questioned and an investigation into the incident is ongoing. The general manager of Club Luxx, confirmed the Talibs were at the club but denied that anything with a gun transpired, the Dallas Morning News reported. Hanney Kamal said: 'One-hundred percent that did not happen. 'I was there. Somebody might have called the police because there was a yelling argument. Talib signed a six-year, $57 million contract last year . 'It's athletes — someone sees them yelling and dials 911. 'Everyone was asked to leave the club, which they did of their own free will, and that was it.' Broncos vice president of public relations Patrick Smyth said: 'We have been in touch with Aqib regarding these reports and will continue to monitor this situation.' Dallas police falsely reported Talib had been arrested for throwing bottles last June during an NFL camp afterparty, the Denver Post reported. The police apologized after it ended up being Yaqub who was arrested. During the 2011 incident in Garland, felony warrants were issued for Talib and his mother Okolo Talib on charges of aggravated assault with a deadly weapon. Police suspected them both of firing shots from a Ruger .380 handgun at Shannon Billings, the boyfriend of Talib's sister, and also believed the NFL back attempted to pistol-whip Billings with a Springfield 9mm semiautomatic handgun during the incident, the Boston Globe reported. They had apparently learned Billings was being physically abusive towards their family member. Talib, who owned both weapons. reportedly yelled during the pistol-whipping: 'You're going to make me throw away my career.' The charges were dropped because prosecutors believed Billings, a registered sex offender with the state of Texas, would not make a credible witness. Garland Police spokesman Joe Harn said: 'It was very fortunate no one was killed and no one was hurt seriously. 'There wasn't a great deal of distance from one person to the other that was shooting.' After the 2011 incident, a felony warrant was issued for  Okolo Talib for an assault with a deadly weapon charge . In addition to playing for the Broncos, Talib has also played for the New England Patriots and Tampa Bay Bucs . In addition to the gun incidents, Talib was investigated after an alleged assault on a Florida cab driver. He then resisted arrest on charges of simple battery. The shutdown corner also fought with teammates and was suspended for violating the NFL's policy on performance-enhancing substances. Talib signed a six-year, $57 million contract with Denver in March 2014. He also has played for the New England Patriots during his seven-year career. During his time with the reigning Super Bowl champs, Talib said: 'I'm a competitor on the field, man. 'That's kind of what we're talking about right now, just football.' If charges are brought with regard to the incident in Dallas, Talib could face discipline under the NFL's personal conduct policy and a suspension seems possible given his history.
