ALLENTOWN, Pa. -

An Allentown man claimed he was defending himself when he slashed a woman across the face late Thursday night.

Allentown police charged Adam A. Ali, of the 500 block of North Fountain Street, with single counts of aggravated and simple assault. District Judge Michael D’Amore arraigned the 25-year-old Friday morning, setting bail at $50,000 with a 10 percent cash option.

Police were dispatched to Ali’s North Fountain Street home for reports of an attack involving a knife. Officers were re-routed to Sacred Heart Hospital, where they met the victim who was bleeding and suffering from a severely swollen face.

She also had a slash wound that went from under her right eye to over the bridge of her nose.

The victim told authorities that she was walking Ali’s girlfriend home, when he came out of the house and punched her in the face, knocking her down and disorienting her. She said she managed to escape and had a friend drive her to the hospital.

Court records do not indicate what precipitated the attack.

Ali allegedly told police that he was defending himself against the woman when he slashed her with his black folding knife. Officers found the knife in his pants pocket.

Ali was sent to Lehigh County Jail after failing to post bail. His next court date is a preliminary hearing tentatively scheduled for Sept. 23.
