A Florida sheriff's stern message to drug dealers is going viral after the release of a video featuring undercover officers wearing ski masks.

"To the dealers that are pushing this poison, I have a message for you: we’re coming for you," said Lake County Sheriff Peyton Grinnell.

Grinnell said his office is receiving more and more calls about heroin-related overdoses, urging residents to call in tips about suspected drug dealers.

Speaking to the dealers in the county, he said undercover officers have already bought drugs from some of them and arrest warrants were being finalized.

The video has generated some backlash on social media, with critics comparing it to ISIS and arguing that it points to police departments becoming too militarized.

Grinnell said Tuesday in an interview with Steve Doocy that the four masked officers wanted to be in the video, but their identities had to be protected under state law.

"They have a passion to serve. They want the county to be safe," he said.
