A Middlesex County grand jury on Friday handed up indictments against an Encore Boston Harbor card dealer and two other people in connection with an alleged scam to pilfer $23,500 over two nights by cheating at the game of baccarat, state Attorney General Maura Healey’s office said.

In a statement, Healey’s office identified the Encore dealer as Jianming Li, 53, of Delaware, and Li’s two co-defendants as Jun Zhang, 41, of New York, and De Lin, 46, of Philadelphia. Online state court records didn’t list attorneys for any of the defendants.

Healey’s office said Li, the Encore dealer, allegedly colluded with Zhang, a former Maryland casino dealer, and Lin in the scheme.

“It is alleged that while he was dealing the cards, Li exposed a series of playing cards, memorized them, marked them with a ‘bookmark’ card, then used his cell phone to communicate the cards and their order to Zhang, when both excused themselves to use separate bathrooms,” the statement said.
