Police documents detail what was found on 2 Chainz' tour bus following the nine hour standoff in Oklahoma City that led to the arrest of the "Feds Watching" rapper and 10 other men. According to TMZ, there were two semi-automatic pistols, a 12-gauge pump shotgun, prescription painkillers, grinders with weed residue, rolling papers and scales.

So far no charges for the findings have been filed.

2 Chainz was on the America's Most Wanted Tour with Lil Wayne and T.I. when his tour bus was pulled over last month (Aug. 22) while leaving their Oklahoma City show. Cops cited that the taillights were out and said that when they approached the vehicle they smelled weed.

The cops then attempted to search the bus, but were locked out and denied entry. They towed the bus to a nearby police yard — with the passengers inside — until a search warrant was obtained. All 11 passengers were arrested, 10 for interference with a police investigation, one for suspicion of drug use; and were released on bail not long afterward.

2 Chainz continued his jaunt around the nation. The tour wrapped up this past Monday night (Sept. 2) in California.
