Matthew Scheidt, 18, was arrested Thursday in South Beach after he pulled his vehicle, which resembled an unmarked police car, next to an undercover police officer sitting in a vehicle, the Orlando Sentinel reported Friday.

Police said Scheidt was found to be in possession of an Osceola County sheriff's badge, deputies' T-shirts, a .380-caliber Ruger handgun loaded with hollow-point bullets, a Taser X26 stun gun, a folding knife, handcuffs, a Motorola police radio and an ankle holster. Charges against Scheidt include grand theft, police said. The teenager is still awaiting trial on two counts of impersonating a physician's assistant and four counts of practicing medicine without a license. Read More Man who posed as teen pleads guilty
