HOUSTON (CBS Houston) A man accused of selling fake Justin Bieber tickets will spend the next eight years in prison. Robert Grusczynski who pleaded guilty Thursday to forgery, would have been sentenced to more time if it were not for the plea deal he reached, according to the judge in the case.

Montgomery County sheriff’s deputies stated that Grusczynski advertised tickets to Justin Bieber’s October 30th concert  in Houston on Craigslist, using the pseudonym of Michael Miller. He sold seats that did not exist and sold those same seats to five separate individuals.

One victim of Grusczynski’s paid $300 for for two tickets; the tickets were to be a surprise for the victim’s daughter.

Authorities learned that the victims met with Grusczynski in the parking lot of a restaurant in The Woodlands, purchasing two tickets to the concert and believing they were authentic. The victims later learned that the tickets were fake and filed reports with the Montgomery County Sheriff’s Office.

Officials with the U.S. Marshal’s Office arrested Gruszynski November 16 near Houston.

With none of Grusczynski’s victims in court Thursday, the judge told him that his victims saved up hard-earned money to purchase tickets for loved ones to see a world-class entertainer.

Additional reports indicate that Grusczynski has a criminal history that includes theft, check fraud and counterfeiting.

Bieber’s concert in Houston was with singer Carly Rae Jepson at the Toyota Center. Ticket prices ranged from $39.50 to $89.50.
