(CBS/AP) NEW YORK - A naked man went on a stabbing spree in his New York City apartment building Tuesday killing an elderly man and injuring four others, police say.

Police say they arrested the 23-year-old Christian Falero Tuesday and charged him with second-degree murder and robbery after he knocked on several doors of his apartment building in the Washington Heights section of Manhattan and then stabbed the people who answered..

 Police say a knife was recovered.

A second-floor tenant, Ignacio Reyes-Collazo, 81, was killed during the random attacks that unfolded around 4 p.m. Tuesday. Three women, ages 60 to 85, were stabbed and a 22-year-old home attendant was punched, police said. 

They were all taken to area hospitals; one was in critical condition while the other three were stable.

Residents said afterward that the suspect was seen running down the street yelling that it was the end of the world. He underwent a psychiatric evaluation at Harlem Hospital, police said.

His fifth-floor neighbor, 41-year-old Ramon Acosta, says he's known Falero for 10 years and he always seemed likable.

"I guess he just flipped," he said.
