Firefighters set up lights as responders converged on the area near Green Street in Teterboro at the South Hackensack border after receiving the report following a motor vehicle accident in Hasbrouck Heights shortly before 5:30 p.m., they said.
The responders combed the area intensively before canceling an ambulance.
"It appears unfounded," a ranking officer told Daily Voice just after 6 p.m.
They continued searching for another half hour, to be sure, before clearing the scene.
Police from Hasbrouck Heights, Moonachie and South Hackensack were among the responders.
