The attack happened this morning before 9 inside 1 Haven Plaza on Avenue C near 12th Street.
The suspect, who lives on the 19th floor, reportedly ran down to the 8th floor where he stabbed a man and his daughter, who is deaf, following a dispute.
Per the Post: "The suspect, in his 30s, who neighbors say lives on the 19th floor with his mother and suffers from mental-health issues, was taken into police custody after he led officers on a brief chase."
It was not clear what led to the attack. The victims were taken to Bellevue.
Per one report:
Friends told NBC 4 New York at the scene that the suspected stabber had texted a friend several days ago that he was going to "snap" and wanted to go back into the church where he wanted to be a minister. He may have recently broken up with his girlfriend.
The suspect and the male victim were martial arts partners and played music together, friends said.
