LANHAM, Md. (CBSDC) — After 400 koi fish were stolen from a pond in a Herndon, Va., office park, police are searching for two suspects.

The fish were removed from the pond near 2411 Dulles Corner Park on at least four occasions in June, Fairfax County police say.

Employees told authorities that two men, calling themselves pond maintenance workers, said they were checking on the health of the fish. They claimed that they were removing unhealthy fish and leaving the healthy ones behind. They were seen scooping the fish with large nets and placing them into coolers between 1 p.m. and 4 p.m. on June 8, 9, 15 and 16.

Eventually employees realized that the men, described as being Caucasian and in their 50s, were not who they claimed to be and contacted police.

Anyone who may have seen the men is asked to contact Detective S.D. Gaydos at the Fair Oaks Police District, 703-591-0966 ext. 5004.
