CHICAGO (CBS) — A man pulled out a gun in the middle of the afternoon in the middle of a Chicago convenience store, all apparently because of a soda tax in an incident captured on the stores surveillance cameras.

Police say Nahshon Shelton, 36, pulled out a blue-steel Intratec .22-caliber submachine gun and threatened to kill everyone in the store.

CBS 2’s Roseanne Tellez reports family members are counting their blessings.

After ranting for several minutes, the man pulls a submachine gun from his satchel. Watch as patrons about to enter, back away cautiously.

Sabry Malahee showed CBS 2 the surveillance video.

“He was saying to my co-worker that he’s going to shoot him in the head three times if he doesn’t stop working here because he charged him the tax for the soda,” said Malahee.

Malahee says when police hadn’t shown up after five calls, he ventured out from behind the glass to confront the man.

“I was asking what does he want because we have a lot of customers and he’s scaring everybody,” said Malahee.

But Malahee says he was not scared.

“When it’s your time, it’s your time. If he was gonna shoot, he was gonna do it,” said Malahee. “After he left I was like, that was so crazy.”

Shelton is now facing aggravated assault charges. Police say that gun had eight live rounds in one magazine, five in another, and one in the chamber.
