A 23-year-old man has been arrested for slashing an elderly man in Greenwich Village, police said. Tylek McPherson was nabbed Tuesday after he got into an argument with the 67-year-old victim, slashing him in the face and hand near Astor Place and East Eighth St. around 2:43 a.m. He faces charges of assault, resisting arrest and criminal possession of a weapon. McPherson was apprehended after the attack; it’s unclear what sparked the clash. He awaits arraignment at Manhattan Criminal Court. The victim was taken to Bellevue hospital and is in stable condition, officials said. McPherson had two warrants for his arrest and is currently on parole for robbery.
