An informant's tip led to the arrest of two central Florida men who authorities say were planning an attack on a police department using a rocket propelled grenade launcher and missiles.

The Marion County Sheriff's Office reported Monday that the informant advised them last week that 32-year-old Christopher Conger and 29-year-old Jeremy Robertson planned the attack against the Eustis Police Department because of recent run-ins with officers.

“We haven’t been able to link them to any kind of group,” Major Terry Brevard told My Fox Orlando. “There is some sophistication to this outfit.”

Authorities served a search warrant and found 22 firearms, several containers of black powder, bullet proof vests, drugs and drug paraphernalia. No rocket launcher or missiles were found, but both men were charged early Saturday on various drug and weapons charges.

In addition to targeting the police, the suspects were planning an attack against a church, investigators said.

According to My Fox Orlando, Conger and Robertson were arrested on multiple charges, including grand theft of a firearm, possession of bullet proof vest during a drug offense, and possession of a firearm during commission of felony, along with numerous drug charges.

Both men remain in Marion County jail on more than $20,000 bond apiece. Neither has yet to obtain an attorney.

“You can’t sit on a tip like this,” Marion County Sheriff Chris Blair told My Fox Orlando. “We’ve got the best of the best here.”
