The owners said in the post someone cut electrical cables and stole the ComEd electric meter on Oct. 4.
An unsigned note with an anti-vaccine message was also taped to the empty meter box, the post said.
Then on Oct. 17, the owners said someone spray-painted white supremacist symbols and graffiti across the venue's front windows and door.
The owners said it's their duty to make the public aware for its safety and the venue has added extra security and installed perimeter cameras.
Chicago police say no one has been arrested, but detectives are investigating.
The owners encourage anyone with information to contact the Chicago FBI office or 14th District Police.
