U.S. immigration authorities say they have deported a Salvadoran gang member wanted in his country in the slaying of a government prosecutor.

Immigration and Customs Enforcement says 21-year-old Javier Arnoldo Ceron Gomez was flown from Mesa, Arizona, to San Salvador Friday and turned over to authorities.

Immigration officials say they were notified by Interpol in June the MS-13 gang member was wanted in connection with the March shooting death of prosecuting attorney Andres Ernesto Oliva Tejada.

ICE says Ceron was arrested a week later at a car dealership in Santa Ana, California, where he worked washing cars.

ICE says Ceron entered the country illegally in April so he was placed in deportation proceedings, where a judge ruled he should be returned to El Salvador.

Another suspect in Oliva's slaying was already deported.
