Myles J. Connor Jr., 69, who once told the FBI that he could secure the return of $300 million in paintings stolen from Boston's Isabella Stewart Gardner Museum if they gave him $5 million, is now at the Adult Correctional Institutions after his arrest last Thursday on charges of robbing two women in front of a convenience store.

Detective Sgt. Matt Ryan said Connor and his girlfriend, Suzanne King, 48, both of Blackstone, Mass., are being held without bail and charged with first degree armed robbery, after they took the cell phone of one of the women.

"He believed one of the women owed him money, and said he was taking the cell phone as collateral," Ryan said.
