The initial report involved someone possibly firing at a vehicle near the corner of Maple Street and Pierre Avenue in Garfield and then running off around 10:30 a.m., possibly into Lodi, responders said.
Authorities couldn't confirm a witness's report that it resulted from a botched attempted robbery of a drug dealer.
No injured victim was immediately found. Area hospitals were checked, but no one came in with a gunshot wound, authorities said.
Uram said the concern was focused on an apartment at that corner. A Daily Voice photo (above) shows an officer with his service weapon trained on the building.
Joining city police were a Bergen County Regional SWAT team, a county Regional Crisis Negotiation Team and a Bergen County Sheriff's K-9 unit.
The city DPW was asked to place barricades closing certain area roads. The barriers were removed a little over two hours later.
The Abraham Lincoln (6) and Roosevelt (7) schools in Garfield and the Thomas Jefferson Middle School in Lodi were temporarily sheltered in place. These were lifted once the area was cleared, Uram said.
Anyone who might have seen something or has surveillance video or information that could help the investigation is asked to contact Garfield PD: (973) 478-8500.
