A Maryland man has been charged with threatening, on multiple occasions, to attack a Baltimore-area synagogue and kill members of the congregation.

Prosecutors allege that Stephen Orback, 65, made numerous phone calls between May 12 and July 21, 2019, to an employee of a synagogue in Owings Mills, Md., and threatened to burn down the place of worship and use firearms and explosives to attack worshippers, according to a superseding indictment.
