The man, identified as Inman Morales, 35, fell about 10 feet from a ledge outside his apartment Wednesday and suffered serious head trauma, medical personnel told The New York Times. He later died.
Police were called by Morales' mother who reportedly found him acting strangely, running naked through his apartment screaming, The New York Times reported. Witnesses told the newspaper the man was swinging a tube light bulb, hitting one officer.
The New York Post, which posted a video of the incident on its Web site, said Morales apparently had an argument with his mother a few hours before police were called. While on the ledge, Morales yelled: "I'm going to die. You're all going to die with me," the Post report said.
After a standoff of about half an hour, police used a stun gun to try to subdue the man. Morales then fell off the ledge.
Morales' mother, who was at the scene, told another building tenant that Morales had stopped taking prescribed medication, the Times said.
