Police have arrested a man accused of hurling homemade firebombs from a Queens rooftop after slashing someone with a machete on a nearby street.

Police say Felipe Velasquez is being held at a hospital where he was taken for a psychiatric evaluation after the incident Tuesday evening. The 21-year-old has been arrested on charges including attempted murder, reckless endangerment and assault.

No telephone number could be found at the Queens address Velasquez gave police. They aren't certain whether he has a lawyer.

Police say Velasquez tossed five flaming, liquid-filled containers into the street from a building roof, setting a car on fire.

Police say Velasquez ran to the roof after using the machete to attack a 45-year-old man on the street below. The victim is hospitalized in stable condition.
