NEW ORLEANS -- 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.

None of the injuries was life-threatening, officials said.
The incident occurred near the intersection of Orleans and Carrollton Avenues where the Krewe of Endymion parade was underway.

• "I saw the gray truck flying down Carrollton Avenue," a female witness told WDSU while clutching her strands of Mardi Gras beads. "He sped up and he lost control and you could see (the truck) was getting ready to turn and I knew he was going to run into all those people."

• The parade was coming down Orleans Avenue before making a right onto Carrollton.
The Endymion parade is one of the most popular 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, included three dozen tractor-drawn floats, some of them double- and triple-deckers.
"With 81 floats, 3,200 riders, and a budget of $7 million, Endymion is the largest Mardi Gras parade. It is also the only parade to roll on a route from Mid-City to downtown New Orleans," reported NOLA.com.
The annual parade is marked by its massive floats, many decorated with neon lettering, large and glowing fleurs-de-lis, big video screens and even spotlights shooting into the sky.
The size of the floats allows hundreds of people to ride on some of them, and the riders -- some dressed in tuxedos, others wearing masks and costumes -- continually toss beads and necklaces to the thick crowd.
Mardi Gras, French for "Fat Tuesday," is a day of revelry that includes parades, parties and gastronomic indulgence before the Christian fasting season of Lent begins on Ash Wednesday. It marks the last day of the Carnival season.
Mardi Gras has also come to refer to the weekend of parties and celebrations immediately preceding Lent.
The day is also called Shrove Tuesday, Carnival Tuesday or Pancake Tuesday, depending on where the celebration is taking place.
