Forty-six-year-old Thomas Brodnicki entered his plea Thursday in Superior Court to one count of stalking. Bail was set at $150,000 and if Brodnicki is convicted he faces up to three years in prison.
Brodnicki is accused of stalking the "Wizards of Waverly Place" star between July and October. Police were notified by mental health workers that he also threatened to harm or kill Gomez while he was on a psychiatric hold.
Gomez was granted a temporary restraining order last month that has been extended to three years.
Brodnicki is scheduled to return to court Nov. 16.
