Man Threatens To Stab Kmart Customers As Black Friday Line Gets Ugly (VIDEO)

One man's frustration with Black Friday crowds reached a boiling point early Friday morning when he was caught on video threatening to stab anyone that came too close to him.

According to CNN, the crowd at a Kmart in Sacramento, Calif. took on a "mob mentality" as the store opened its doors to shoppers who had been in line for hours.

WARNING: Extreme Language

The mood became very tense when store workers started to hand out vouchers to those waiting. Some began to cut the line and shoppers shouted obscenities.

That's when a man started threatening to stab people, Local Fox 40 reports. When other customers laughed, he said he wasn't joking.

“Calm the f**k down! Push one of my kids and I will stab one of you motherf**kers!” the man shouted, according to Mediate.Although the man eventually calmed down, police officers arrived on scene a little after the the doors opened at 6 a.m., to cheers from the crowd.

In Los Angeles, the police department deployed extra officers this holiday season in order to keep the peace at Black Friday havens across the area.

"For some people, shopping is a competitive sport," LAPD Commander Andy Smith told the Los Angeles Times. "But it should not be a contact sport."
