Clubgoer accidentally shot by off-duty FBI agent at Denver club breaks silence

The clubgoer accidentally shot by a dancing, off-duty FBI agent trying to pick up his gun initially believed "some idiot set off a firecracker."

But Thomas Reddington soon realized the G-man struck him in the leg at the Mile High Spirits Tasting Room in Denver after midnight Saturday.

“I'm still thinking it's a firework ... all of a sudden from the knee down my leg became completely red,” Reddington, 24, told ABC News’ “Good Morning America” in an interview set to air Thursday. “And that's when it clicked in my head, oh, I've been shot.”

While Reddington and his friends were at a picnic table in the downtown Denver bar, the agent — identified by ABC News as Chase Bishop — was cutting a rug on the dance floor.

Video of the agent dancing went viral over the weekend, as a handgun flew out of its holster while the lawman was doing a backflip. When the 29-year-old agent went to pick it up, the gun fired a single shot into the unsuspecting Reddington’s leg.

“I heard a loud bang and I thought some idiot set off a firecracker,” Reddington, laid up on a couch with his leg elevated, told ABC News. "Then I looked down at my leg and see some brown residue.”

The agent was taken to a Denver police precinct, and later handed over to an FBI supervisor. Bishop is based in Washington, D.C., sources told the network, and “will be held accountable.”

The bar lambasted the agent for breaking its rules by bringing the loaded gun inside, and previously promised Reddington he can drink for free any time he wants.
