(FoxNews) - A worker at a Napa County wine warehouse was arrested Tuesday after police say he stole more than $400,000 in fine wine and sold some of it on the black market, The San Francisco Chronicle reported.

Police searched Jose Pina’s apartment and say they found $73,150 and 55 cases of the stolen wine. He was reportedly booked on suspicion of grand theft and other charges.

The paper reported that authorities expected an inside job because there was no sign of forced entry at the American Canyon warehouse
