What happened?

• A 72-year-old grandfather was looking out a first-floor window of a New York City apartment building about 7 a.m. Sept. 29 when he noticed a man going through the garbage, the New York Daily News reported.
• The granddad — whose wife is the superintendent of the Chelsea building — went outside to investigate, the paper said.
• He told the Daily News he found the man squatting on a staircase leading to a basement apartment.
• “He had his pants down to make poop-poop,” said the grandfather, who spoke to the paper on the condition of anonymity. “He pulled his pants up and went upstairs."
• The granddad added to the Daily News that he "kicked him" — and then the man "swung around with something in his hand.”
• “I couldn’t tell what it was, a knife or what, but I saw the point,” the victim told the paper. “It went right through my jacket and shirt and it cut me down the side.”
• The 4-inch slash required stitches, the Daily News reported, adding that the attacker ran off.

How is the victim reacting?

• “I’m scared,” he told the paper. “I wake up all the time worrying about whether he'll come back.”

What's the suspect's description?

• Police described the man as black, between 50 and 60 years old, about 5 feet 8 inches tall, weighing about 150 pounds, wearing a black baseball cap and black hoodie and with a dirty appearance.
