April 5 (UPI) -- A 57-year-old man stands charged with driving his car into a crowd of parade-goers in southern Louisiana while drunk and causing multiple injuries, authorities say.

Todd Landry, of Jeanerette, La., was arrested Saturday after "striking multiple pedestrians" during the Lao New Year Parade in Broussard, La., located about seven miles south of Lafayette, La., in Iberia Parish, according to Louisiana State Police.

The exact number of people injured in the 2:30 p.m. incident remained unconfirmed on Sunday but Acadian Ambulance reported it transported a total of 11 patients by ground and two patients by air to nearby hospitals.

State troopers said they arrested Landry and booked him into the Iberia Parish jail on 18 counts of first-degree negligent injuring, one count of first-offense driving while impaired, careless operation of a vehicle and having an open container of alcohol in his car.

"Based on the preliminary investigation, this does not appear to be an intentional act," the sheriff's office said in a statement.
