ATLANTA (AP) — The FBI is investigating who possibly hacked an electronic billboard after it displayed a pornographic image in Georgia.

WSB-TV (http://bit.ly/1FmfUMu) reports an electronic advertisement billboard in Buckhead displayed a graphic picture of a man exposing himself among other images Saturday. A driver who saw the image called 911. The woman said there was not an emergency but the image was disgusting.

Police say the billboard's owner temporarily cut power to the billboard, but not before the image had been posted to social media.

Wednesday, an FBI representative told the station agents are trying to determine all of the servers involved in the apparent hacking and their locations.

The president of Georgia's Outdoor Advertising Association says the industry has established protocols to prevent hacking of digital billboards.
