The incident was reported Saturday just after 1 a.m. in the East Harlem borough of Manhattan.
Video released Wednesday shows the 19-year-old victim running for his life as he was chased by two men while one held what appears to be a machete.
When the victim stumbled, his attackers pounced and struck him three times before he escaped into a bodega. A store worker locked the door and helped the victim by blocking the suspects from getting into the store.
When officers arrived, one was already wearing gloves and immediately tended to the victim who has blood gushing from both arms.
The cops took out tourniquets and applied them to each arm, then walked him out of the store and drove him to the hospital.

The suspect with the sharp object was later arrested and charged. He was identified as 19-year-old Abner Suazo and faces charges of assault, criminal possession of a weapon, and menacing.
Suazo was arrested twice in 2019, once for assault in July and once for criminal possession of a weapon in November.
The victim is expected to make a full recovery.
