The State College Police Department often advises staff at downtown bars to call police if a patron is refusing to leave. Early Sunday morning, staff at one establishment found out why.

The incident occurred at about 12:09 a.m. at the Shandygaff, 212 E. College Ave. Bar staff asked a 31-year-old Bellefonte man to leave several times, police said, but he did not want to and was argumentative.

As two staff members escorted the man out, police said the man lunged forward and headbutted a 24-year-old male employee.

Police said the employee, a bartender, suffered a bloody nose, but was not taken to the hospital.

The Bellefonte man was cited for harassment, police said. His name was not available as of press time because his charges had not been processed.

Police said they tell bar staff to call the department if they need help dealing with particularly unruly customers. If the man had struck — or even attempted to strike — a police officer, he would automatically face an aggravated assault charge, which is higher in severity than a harassment citation.
