In the end, his identity was not rock-solid.
Garden City Village police said they arrested a Brooklyn man Saturday after he impersonated an FBI agent while presenting a forged check to buy a diamond worth nearly $16,000.
According to police, on Oct. 28, Michael Morgan, 51, of Crown Heights, entered HL Gross & Bro. Jewelers at 840 Franklin Ave. and wanted to purchase a loose diamond for $15,987.43.
Police said Morgan told the clerk he was going to the bank to get a cashier’s check. When he returned, he was wearing an FBI jacket and placed a gold-colored FBI badge on the counter and presented the cashier’s check, police said.
The JPMorgan Chase check was later found to have been forged, police said, adding Morgan impersonated an FBI agent.
After an investigation, Morgan was arrested Saturday.
He is charged with third-degree grand larceny, second-degree possession of a forged instrument and first-degree criminal impersonation. At an arraignment Sunday in Nassau County First District Court in Hempstead, bail for Morgan was set at $20,000 bond or $10,000 cash.
An attorney for Morgan could not be immediately reached.
