Authorities raided nine New York sites and seized 25 pounds of cocaine, a $4 million stash believed to be from the same source as 3 tons of the drug seized last month in the nation's third largest cocaine raid, officials said Saturday.

Federal and local agents arrested 26 people, including three Colombian nationals and two prominent businessman, in the Friday sweep dubbed "Operation Terminate," said Officer David Bloom, a Suffolk County police spokesman.The nine-month investigation was continuing, and police said they expected more arrests.

Besides cocaine, agents from the federal Drug Enforcement Administration and Suffolk County Police also seized two yachts measuring 48 feet and 38 feet, an airplane and a tractor-trailer with a hidden compartment in the refrigerator section that was used to smggle 100 kilograms of the drug from Miami, Bloom said.

Also seized were 15 cars, including Cadillacs, Covettes and BMW's, $20,000 in cash, nine pistols, six rifles, three computers and numberous scales and cocaine processing equipment, he said.
