Local police, FBI and ATF agents report that two 40 ounce bottles with what is believed to be an explosive chemical were found outside of Grand Hustle’s offices Thursday afternoon. Sources say the one of the explosives was thrown through the window of an adjacent recording studio on the property.

A local resident called authorities after finding the bottles on the property. The Atlanta Fire Dept along with the ATF, FBI and the Atlanta SWAT team responded and conducted the investigation on the suspicious items.

No one was injured in the incident. The ATF has taken over the investigation.

“One of the occupants came out early this morning, started his car up and noticed two suspicious bottles sitting on his front porch near the walkway,” Officer Otis Redmond said, while talking to WAGA Fox 5. “We did have the ATF and the FBI help us determine the substance inside of the bottles.”

An unnamed Grand Hustle employee dismissed the incident as vandalism. Grand Hustle was formed in 2003 by T.I. and Jason Geter. The label serves as home to 8Ball & MJG, Killer Mike, B.o.B, Young Dro and other artists.
