Video (00:56) : An employee of Haskell's liquor store in downtown Minneapolis took this video of the moment police apprehended Mark D. Erickson after he allegedly sneaked into the back of a beer delivery truck before being locked in by the driver.

A man sneaked into the back of a beer truck behind a liquor store in downtown Minneapolis, intent on stealing some of the inventory, but the driver thwarted the thirsty thief and locked the interloper inside until police arrived, authorities said Thursday.

Mark D. Erickson, 47, was arrested and jailed Wednesday on a misdemeanor charge of tampering with a motor vehicle.

The trouble started brewing for Erickson late Wednesday morning in the alley behind Haskell’s on S. 9th Street just off Nicollet Mall, said store co-owner Beau Farrell.

Erickson climbed into the back of the delivery truck, only to find himself incarcerated by the quick-thinking driver, Farrell said.

“The driver was walking up the ramp” on the back of the truck and was startled to see a much bigger man inside, Farrell said. “[The driver] jumped down, locked the door and called the police.”

Farrell said it was maybe 5 minutes, and police were there to make the arrest and have Erickson again locked up — this time in the Hennepin County jail.

This screen grab from video shows the suspect being arrested.

“Liquid courage” is how Farrell described the man’s gumption. “If it were me, I would have sat down and had me a cold one.”

Farrell said the man had been a regular customer, but now is “in our book of shame” and no longer welcome at Haskell’s.
