LANCASTER, Pa. (AP) — A Pennsylvania man who made threatening phone calls to his former employer has been sentenced to up to 10 years in prison.

Sixty-one-year-old Lewis Watkins, of Lancaster, was sentenced on Tuesday to three to 10 years in prison. Watkins had previously been convicted of stalking and making terroristic threats in June.

Prosecutors say last year Watkins made dozens of calls to the human resources director of a Manheim Township company he was fired from in 2012. Prosecutors say Watkins threatened to appear at the business or the victim's home and do something to "make the news."

Authorities say the human resources director wasn't employed with the company when Watkins was fired.

Officials say the company had to increase security after Watkins made threats.
