SAN FRANCISCO — A federal judge handed down a yearlong federal prison term for a South San Francisco man convicted of tax fraud for concealing around $400,000 he made during a scheme he and a fellow prisoner hatched while he was serving time for a previous fraud conviction.

Robert Stein, also known as Mikhail Solovey and Michael Swarovski, 56, pleaded guilty last year and agreed to provide information about the scheme to prosecutors, which the assistant U.S. attorney commended him for at his Friday morning sentencing. Stein’s partner in the prison fraud scheme died before prosecutors could charge them in that case, so he avoided potentially more serious charges.
