The ensuing investigation prompted police to close Seventh Avenue between 42nd and 44th Streets on Monday morning.
The bomb squad determined the object was not a threat and streets were reopened, and detectives said there was no obvious message or threat implied by the object.
Desean Maryat, a 26-year-old Bronx man, was picked up by detectives and taken to a hospital for a psych evaluation before being charged.
The charges against Maryat include reckless endangerment and making terroristic threats.
