Huan Quan Yu, 59, Jiehui Huang, 49, and Raymond Li, 57 were arrested after a week-long investigation by Delaware State Police that began after casino employees and surveillance footage caught on to the trio's scheme. All three men are from New York, although they were carrying California driver's licenses when they were apprehended, officials said.

They face charges of criminal mischief, conspiracy and attempted theft, and officials suspect that the three are linked to a larger cheating network based in New York City and San Francisco.

Li and Huang were arraigned, released on bond and court-ordered against entering Delaware casinos. Yu posted bond, but is being held in connection to gaming crimes that he committed in Pennsylvania, and was sent to the Howard R. Young Correctional Institution, in Wilmington.
