Daytona Beach, Fla., police, the FBI, and the Bureau of Alcohol, Tobacco, Firearms and Explosives are conducting a joint investigation into a Facebook post that calls on people to kill law enforcement officers, reports WFTV.
Officials say the post could be fake, but Chief Mike Chitwood said he received more than 500 emails about the threats.
The post, belonging to Jammal Longmire, calls for people to pick up guns and kill police officers, police said.
Police said the man in the picture is holding two assault rifles.
"Is this really an attack on the officers? Is this person on that Facebook really who they say they are? So that's what the investigation is trying to show out," Chitwood said.
Officials said there are three posts on Longmire’s page that, real or not, have forced Chitwood to place all his officers on high alert.
