TULSA, Oklahoma - Police are questioning a man they arrested after a three-hour standoff at the Dollar General near Admiral and Harvard.

Investigators say Treveon Vaughn also confessed to several other robberies this year.

Police said around 8:00 Friday morning, a man armed with a gun and dressed in black went into the store to rob it. The employees were able to escape, leaving the suspect inside the store alone.

Police also believe a getaway driver left Vaughn at the scene.

Tactical teams got in place, guns were drawn, and the police chopper flew above as Tulsa's Special Operations Team worked to get the robbery suspect out of the store.

"You don't have to rob, steal and kill from people just to get what you want. There's help out there," witness Crystal Turner said.

She said her cousin was one of the cashiers who was inside when it happened.

"I don't know why people can't get jobs instead of robbing, stealing and killing from people. It's sad," Turner said.

During the three-hour standoff, police said Vaughn started a fire, activating the store’s sprinkler system, so police called in the fire department.

"We see cops up here about two to three times a week just for Dollar General," witness Fred Lollis said.

Lollis and his wife couldn't help but wondered what the commotion was.

"I do know that there's a lot of stuff that happens at the Dollar General, and the store manager is always having to come out and chase people down almost daily," he said.

Vaughn eventually surrendered peacefully.

"He did come out of the store peacefully which is what we wanted to happen," Officer Jeanne Mackenzie said. “We wanted him to come out. We didn't want anybody hurt or injured. We didn't want the officers hurt or injured, so it was a very successful operation for us."

Police are still looking for the get-away driver.
