TMZ Sports has obtained photos from inside the Dallas strip club where Denver Broncos star Aqib Talib may or may not have been shot back in June ... and it's a bloody mess.

Talib was shot on June 5th -- and even though he told police it happened at a nearby park, at least one official police document (obtained by TMZ Sports) lists the "offense location" as V Live strip club.

The photos show trails of blood inside and outside of the club -- along with shattered glass, knocked over furniture and shell casings on the ground.

Cops say at least two other men were shot inside the club that night -- and one of the victims claimed the shooter was a "black male in a white shirt [who] pulled out a handgun and began to fire into the crowd."

The two men (not Talib) were photographed in the hospital by law enforcement that night to document their injuries.

There are reports Talib accidentally shot himself in the leg while trying to pull out his gun -- but Talib has neither confirmed nor denied that.

So far, no arrests have been made.
