(CNN) — One man is in custody after an accident at a Mardi Gras parade in New Orleans injured at least 28 people, five seriously, officials said.
Police Chief Michael Harrison said it appeared the suspect, who was driving a pickup truck that hit two cars before running into the crowd, was likely highly intoxicated. Among the injured, the youngest is 3 and the oldest are in their 40s.
None of the injuries was life-threatening, officials said.
The New Orleans Police Department arrested Neilson Rizzuto, 25. He has been charged with two counts of first-degree vehicular negligence resulting in injury, and one count each of reckless operation and hit-and-run driving.
The incident occurred near the intersection of Orleans and Carrollton Avenues where the Krewe of Endymion parade was underway.
Harrison said there is no indication the accident was an act of terrorism.
Video from CNN affiliate WDSU showed a gray pickup truck that had crashed into a dump truck on a median near the intersection. Witnesses told the station the pickup came down one of the streets and struck several cars before hitting people in the crowd watching the parade.
"I saw the gray truck flying down Carrollton Avenue," a female witness told WDSU. "He sped up and he lost control and you could see was getting ready to turn and I knew he was going to run into all those people."
The Endymion parade is one of the biggest parades leading up to Mardi Gras, which is Tuesday, and one of the most family-oriented. Many parents brought their children to the event.
The parade, held in the Mid-City neighborhood far from the French Quarter, includes three dozen tractor-drawn floats, some of them double- and triple-deckers.
