BOYNTON BEACH, Fla. – A Florida teen was arrested after he reportedly stole an AR-15 and tactical gear from an unmarked Palm Beach Sheriff’s deputy’s vehicle, officials said Sunday.

A 17-year-old of Boynton Beach, flaunted the stolen weapon on an Instagram Live stream as he danced to rap music, the Miami Herald reported, citing a probable cause affidavit.

The deputy reported the items stolen to Boynton Beach police on Aug. 14. He left his unmarked police unit parked at a shopping plaza for several hours, according to the newspaper. In addition to the AR-15, the thief took two loaded magazines, a gas mask, Taser, ballistic helmet and rifle clips, police said.

Police say that although footage shows the suspect, Clay Moses, leaving the parking lot in a car that they later discovered in the area, it was the social media post that gave investigators sufficient probable cause to obtain a search warrant, the Herald reported.

As a result, detectives served the warrant and found the stolen items under Moses’ mattress, police said.

Consequently, Moses faces grand theft and burglary with firearm charges and was being held at a juvenile detention center.
