Police in Providence, R.I., say an unmarked car that officers had been driving for several years came with a surprise — a half-pound of cocaine hidden behind the radio.

Deputy Police Chief Paul Kennedy said the Ford Taurus was confiscated from a drug dealer in 2000.

Police do search for contraband in confiscated vehicles but sometimes they "miss stuff," Kennedy said.

Three packages of cocaine were found behind the dashboard about three weeks ago by a repairman who was cannibalizing the car for spare parts.

Police estimated the stash would be worth almost $7,000 on the street.

Kennedy said it's unlikely anyone will face charges over the concealed coke.
