Jose Rios, 51, used a gun in two holdups and a knife in another, state Attorney General Gurbir S. Grewal said.
After suggesting that he could be infected, Rios of Jersey City said that police would soon find out – then spit at one of them, Grewal said.
Police charged him with three counts of armed robbery and several of illegal weapons possession for the May 2 and May 9 holdups, then sent him to the county lockup to await a hearing, the attorney general said.
