NEW ORLEANS, La (NBC33) — An RTA bus carrying 15 people was fired upon Thursday, causing an 18-year-old man to be injured with a gunshot wound to the arm, a frantic late-afternoon scene on one of the city's busier streets and public officials to roam a closed-off section of Carrollton Avenue.

Two men were chased down and arrested after 911 calls from passengers offered tips following the frightening ordeal which took place at the bus stop on Carrollton and Washington where the gunfire erupted after two men exited and one opened fire, aiming at a rival still on board, New Orleans Police said.

Davanta Davis, 17, and and Codero Johnson, 23, are in Orleans Parish Prison for their alleged roll in the incident. Davis is the accused shooter and Johnson is said to be his accomplice.

After the shots were fired, the pair sprinted off, before being caught.

Police from nearby Xavier University assisted the NOPD at the crime scene, which also featured visits from NOPD Superintendent Ronal Serpas, city Director of Homeland Security, Lt. Col. Jerry Sneed and RTA CEO, Justin Augustine.

Augustine credited the bus driver for pulling forward after his glass was pierced by a flying bullet, a move the CEO said took passengers out of continued danger.

There is still no word from detectives as to what the beef was on board the bus leading to the gunfire.
