One person was shot inside an Oklahoma mall Thursday, prompting law enforcement to clear the building in the middle of a busy holiday shopping season.

Officers got a call just before 4 p.m. in response to the shooting which unfolded during a dispute at the Penn Square Mall, the Oklahoma City Police Department tweeted.

"At this time, we’ve located one shooting victim from the incident [at Penn Square Mall]," the department said. "This appears to be an isolated incident that began as a disturbance between individuals."

Details about the shooting were not released immediately, but the Oklahoman newspaper reported that one person was shot in the chest, per police, and was rushed to a hospital. The person's condition was unclear.

The suspected gunman was seen fleeing from an area near a Foot Locker but it was not clear where he went, police said. He was described as a black male wearing grey sweatpants and no shirt.

Officers were still working to clear out the mall, police said.

The shopping center was locked down but shoppers were seen leaving from the south side of the building, according to the newspaper. Fox News' calls and messages to the Oklahoma City Police Department were not returned.

Oklahoma City SWAT officers were seen staging outside the shopping center.

The Oklahoma Highway Patrol said it closed off-ramps on Interstate 44 leading to the mall.

Kaity Sharp, a student at Central Oklahoma University, told the newspaper she was inside a Sephora on the mall's second floor when they were rushed into a stockroom.

"I didn't hear shots, but other people in here said they did," Sharp said. "They told us they're letting people go, but we were told to stay here."
