A California man has been sentenced to four years in prison for smuggling $3 million worth of opium that was concealed in hollow wooden picture frames.

Mohsen Youssefinejad of Lake Forest was convicted by a jury in February of two drug-related felonies for receiving 14 pounds of the drug via mail to his Santa Ana business.

Customs officials found the drug stuffed into decorative frames in New York, but monitored its delivery to Youssefinejad.

When he picked up the crate on June 9, he was arrested.
