HERNDON, Va. (AP) - These crooks are anything but coy. Authorities in a Washington suburb are investigating the rip-off of hundreds of koi fish from a business park pond. Fairfax County, Virginia, police say about 400 of the colorful fish were scooped out of the pond. Authorities say fish were stolen on at least four occasions this month. Witnesses tell police two men claimed to have been maintenance workers checking on the fish and removing the unhealthy ones. The fish were taken out of the pond with nets and put in coolers. The witnesses called the cops after realizing something was fishy.
