Pennsylvania prosecutors say six men face drug charges after investigators seized more than a quarter-ton of cocaine from a Philadelphia warehouse and two vehicles.

Authorities allege they were part of a drug ring that smuggled cocaine from Puerto Rico and the Dominican Republic to the United States.

They estimate the 232 kilograms, or more than 500 pounds, of cocaine recovered Monday had a street value of $23 million.

The defendants are from Pennsylvania, New York, Florida and Puerto Rico.

All are jailed with bail set at $1 million or more.
