A gunman opened fire at a Walmart superstore in the US state of Ohio, injuring four people before killing himself, police said.
The incident happened Monday evening in Beavercreek, a town of about 46,000 people.
“A man entered the Beavercreek Walmart around 8:35 p.m. Monday (01:35 GMT, Tuesday) and began shooting a gun, injuring four people,” Beavercreek police said in a statement posted on social media.
Witnesses told local media that the man opened fire with an assault rifle.
“The victims were transported to area hospitals and their conditions are unknown at this time,” Beavercreek police said. “A fifth person, the shooter, died from an apparent self-inflicted gunshot wound.”
Police said no shots were fired by responding officers, the building was cleared and secured a short time later and no active threat remained.
The shooter’s name, motive for the attack and other details were not immediately released.
Footage from the scene showed a phalanx of police cars with their lights flashing converging on the store.
“I was literally buying stuff for Thanksgiving and this guy walked past me with an assault rifle and started shooting,” one woman said in a video posted to social media.
“I ran… He shot about 10 times… I’m so lucky to be alive,” she said.
Another witness on social media described the attacker as a “tall young white man” carrying a military bag.
“My nerves are on edge right now,” she said.
Soin Medical Center in Beavercreek received three patients, said Catherine Morris, a spokeswoman for parent company Kettering Health.
“We are heartbroken by what happened at our store in Beavercreek, Ohio. The situation remains evolving and we are working closely with on-site investigators,” a Walmart spokesperson told local media outlet WHIO-TV.
Beavercreek police said, “Our thoughts and prayers are with the victims and families affected by this horrific tragedy. We will release more information as it becomes available.
