A northeastern Pennsylvania man who injected his semen into the yogurt of two co-workers has been sentenced to two years in prison.

Sixty-year-old Joseph Bartorillo of Larksville pleaded guilty to a federal charge of tampering with a consumer product. He was sentenced Tuesday in Scranton.

Prosecutors say Bartorillo injected yogurt containers of co-workers at the Procter & Gamble plant in Wyoming County at least 13 times between October 2009 and May 2011.

His attorney, Demetrius Fannick, tells The Times Leader of Wilkes-Barre that Bartorillo apologized to the victims but did not offer any explanation.

He still faces state charges.
