The victim, from Spring Valley, was conscious and alert but had a large cut on his forehead when officers arrived at the Wyckoff Avenue home shortly after 8 p.m., Mahwah Police Chief Stephen Jaffe said.
He'd been helping his friend remove a branch that fell earlier, the chief said.
The officers controlled the bleeding until Mahwah EMS and an ALS unit from the Valley Hospital arrived, Jaffe said.
Mahwah’s rig took the victim to Hackensack University Medical Center, he said.
