An 18-year-old Philadelphia man has been charged in Berks County with the stabbing of a Kutztown University student earlier this month.

Robert Centifanti, who police said is not a Kutztown University student, was charged Friday afternoon with attempted homicide and attempted first- and third-degree murder in the Feb. 20 incident. He was being held at the Berks County Jail on $50,000 bail.

The victim, a 23-year-old man, remained in serious condition. Kutztown police have not released his name.

The Reading Eagle reported the stabbing occurred when Centifanti and two other men left a party and one of the other men urinated in an alley. The newspaper, citing court documents, said the victim was stabbed in the neck and chest after warning the man that public urination was "not the best idea because cops give citations all the time."

Centifanti then punched the victim, knocking him to the ground, according to the court documents. The Eagle reported that as he left the scene Centifanti said: "That's how we do it in Philly."

Centifanti, who surrendered to authorities Friday, was in Kutztown visiting friends at the school the day of the incident, police said.

Police said Centifanti was the only person who assaulted and stabbed the victim. Police said no charges against the other two men are anticipated.

Centifanti was also charged with a weapons offense, aggravated simple assault, and recklessly endangering another person.
