Tyson Tomko, Ex-WWE Star Arrested -- Allegedly Shooting Up in a Chili's Bathroom

A former WWE wrestler was arrested in Florida yesterday after cops say he was injecting himself with stolen pain medicine ... while hiding inside the bathroom of a local Chili's restaurant.

Tyson Tomko -- who wrestled in the WWE between 2002 and 2009 -- is accused of robbing a CVS Pharmacy on October 10th ... allegedly threatening to attack the pharmacist unless he forked over several bottles of Oxycodone.

The pharmacist claims he complied -- and Tomko escaped with 210 tablets of the powerful painkiller.

According to the police report, obtained by TMZ, Tomko went to a nearby Chili's ... where he asked his waitress for a spoon. When the server brought him a teaspoon, he asked for a "deeper spoon" ... and when he got it, he took it to the men's room ... where he remained for 30 to 40 minutes.

Cops were eventually tipped off ... and when they arrived on the scene, one officer says Tomko had "needle marks and blood running down his arm" ... and had just flushed something down the toilet.

Tomko was taken into custody -- and allegedly told police he has a "severe drug problem."

Cops say Tomko admitted he took the Oxycodone from CVS ... and injected 178 pills, which he crushed up and melted down ... but he swore he never threatened the pharmacist.

Tomko was taken to a nearby hospital ... then transported to a nearby jail, where he was booked for robbery. He's currently behind bars -- bond was set at $7,500.
