Police who responded to Clay and Second streets near Carver Park found a 35-year-old man with a graze wound around 5:30 p.m. May 23, Bergen County Prosecutor Mark Musella said.
A 40-year-old man, meanwhile, arrived at Hackensack University Medical Center in a private vehicle, the prosecutor said.
His injuries weren't believed to be life-threatening.
A potential suspect wearing a blue hoodie was said to have fled south on 3rd Street in a silver Honda.
Unconfirmed reports were that the vehicle was involved in a crash in Teaneck.
"Omg I just heard like 20 shots," an area resident posted.
One witness said an AR15-type rifle was used. Another said police found a handgun at the scene, suggesting a possible exchange of gunfire.
Hackensack police were joined at the scene by the Bergen County Prosecutor's Major Crimes Unit and the Bergen County Sheriff's Bureau of Criminal Identification, which collected evidence.
Detectives obtained search warrants for at least one and possibly two vehicles, responders said.
