Disney star Billy Unger has been arrested for driving under the influence of alcohol.

The National Treasure: Book of Secrets actor was pulled over for speeding on Saturday in Malibu, California and during the stop, police officers suspected the 18 year old had been drinking and administered a breathalyzer, according to Tmz.com.

Unger blew a .08, the legal limit in the state, but because he was under the legal drinking age of 21, he was arrested for Dui.

He has since been released.
