New Orleans police on Thursday night arrested a 16-year-old boy on allegations that he fired bullets into the air near the corner of St. Charles Avenue and Calliope Street as a Carnival parade passed.

No injuries were reported following an incident that caused screaming people to scurry and stopped the Knights of Chaos parade for about 20 minutes.

The gunfire occurred as a group of about 70 young people walked toward the underpass at St. Charles and Calliope, a popular spot for high school students to gather and watch their marching bands pass. Numerous police officers on foot and horseback were interspersed among the group when what sounded like four gunshots erupted.  

Countless people within earshot began screaming and scrambling. Officers were soon seen questioning a young man who had been handcuffed while other cops used flashlights to scan the ground. 

It appeared they may have been looking for a gun and shell casings. Things returned to normal after about 20 minutes, with people returning to their spots to watch the rest of the parades. 

Police did not release the name of the teen they arrested because he was arrested as a minor. 

Officials did not specify what crime the teen would be booked on. But in Louisiana it is illegal to recklessly discharge a gun within 1,000 feet of a parade. 

Chaos was one of three parades scheduled to roll along the traditional Uptown route Thursday. It was preceded by Babylon and followed by Muses. 

Initially, news of the gunfire caused alarm on social media and among spectators along the route.

The underpass is within two blocks from where a gun battle left two young men dead while parades rolled on the Thursday before Mardi Gras in 2015 and from where another shooting left two teens wounded on the Thursday before Mardi Gras in 2012. 

The underpass is also a little less than a mile from where seven people, including a toddler, were hit by gunfire that erupted on St. Charles on Mardi Gras in 2009.
