Quenton Marselles Brown, the father of Boston Celtics star Jaylen Brown, was arrested following a stabbing in Las Vegas on Wednesday and charged with attempted murder.

The elder Brown had his first court appearance on Thursday, when his bail was set at $300,000, according to multiple reports.

Per an arrest report, the incident took place in a parking lot outside a Las Vegas park. A man and his girlfriend were sitting in their car when an SUV parked beside them. Someone exiting the SUV allegedly dinged the door of the car in the adjacent spot, prompting a confrontation.

The victim’s girlfriend told police that the man purported to be Brown “briskly walked after (the victim) while producing (an) unknown object from his right side.” He swung his arm and struck the victim in the back before hitting him several times in the stomach.

Brown’s attorney told Las Vegas television station KSNV that his client acted in self-defense. They claimed that Brown was hit over the head with a gun, which was not in the police report.

Brown was a professional boxer who became the World Boxing Union (WBU) world champion in 2016. Multiple stories about his boxing days list him as 7 feet tall.
