One person was killed and 24 wounded when gunfire erupted during a car show that is part of an annual community event in a small south-east Arkansas town, authorities said on Sunday.
At least six children were among those wounded.
Police had not said what led to the Saturday night shooting in Dumas, but Governor Asa Hutchinson said on Twitter that there were two suspects, one of whom had been arrested and was being held on unrelated charges.
“As the investigation continues I will examine details to see if there are any steps that could have been taken to prevent this type of tragedy,” Hutchinson said.
Dumas is a city of about 4,000 about 90 miles south of Little Rock. The car show is part of a community event held each spring called Hood-Nic, which is short for neighborhood picnic.
The Hood-Nic Foundation says on its website that its mission is to “rebuild, reunite, and respond to the needs of the youth in our communities”.
The event, which helps raise funds for scholarships and school supplies, also included a bonfire, a basketball tournament, musical performances, a teen party and a balloon release.
“The purpose of Hood-Nic has always been to bring the community together,” the foundation said on its Facebook page. “This senseless violence needs to end.”
Six children were taken to Arkansas Children’s Hospital in Little Rock, according to a spokeswoman. Most had been released by Sunday afternoon.
Messages left at a hospital in Dumas and another in nearby McGehee were not immediately returned.
Wallace McGehee, the car show organizer, expressed condolences to the victims’ families and the community.
“For something like this to happen, it’s a tragedy,” McGehee told KATV. “We did this here for 16 years without a problem.”
Chris Jones, a Democrat running for Arkansas governor, tweeted that he was at the event earlier on Saturday, registering voters and enjoying “a positive family atmosphere”.
“I am deeply saddened (and honestly angered) by this tragedy,” Jones said in a statement.
Hutchinson said the man who was arrested was from Jacksonville, just north-east of Little Rock.
