BERKELEY (CBS/AP) – A purported music entrepreneur now living in Berkeley who bilked a New Jersey investor out of $330,000 by claiming he was promoting a series of Mariah Carey concerts in Dubai has been sentenced to 21 months in federal prison.

Antywan Ross also was sentenced Monday to pay more than $325,000 in restitution.
