SALEM – A man with four aliases and five Social Security numbers was indicted on drug charges in Salem Superior Court on Wednesday and is already under indictment in another drug case.Nelson Bolivar, 45, provided an address of 42 Park St., Salem to police, but gave an address of 100 Tyson St., Lynn, after he was arrested last July. He was indicted on two counts of possession of a Class A substance (heroin) with intent to distribute, illegal possession of a Class A substance (subsequent offense) and two counts of possession with intent to distribute in a school zone.Bolivar was arrested on Jan. 21 as one of three people arrested in separate sting operations conducted by Salem police last month. Police said Bolivar, going by the name “Julio,” met with an undercover officer twice to make drug deals on Bridge Street. He has also used the names Sammy Martinez and Sam Gomez.Bolivar was also arrested last summer after police saw him make a drug deal with a known addict and allegedly spit out three bags of cocaine as he fled from Salem police, Lt. Conrad Prosniewski said.Bolivar said in Spanish during his arraignment that he sometimes stays at the Salem address, but lives in Boston. His attorney said Bolivar is a Puerto Rican native who lives in Roxbury and is a legal resident, but police believe he may be Dominican. If he is not a legal resident, he may be facing deportation, Prosniewski said.Bolivar was ordered held on $50,000 cash bail at his arraignment in District Court last month, but Judge Dominic Paratore granted a request to revoke his bail for the July case, which means Bolivar will not be released even if he is able to make bail.Indictments are a legal formality that transfers a case from Lynn District Court to Superior Court, allowing for a more severe punishment. It is not an indication of guilt.
