Harrowing video exhibits a 15-year-old Bronx boy working for his life before he collapsed and later died in a capturing his dad believes is tied to ongoing bullying at faculty.

Javits Frimpong was seen sprinting through his Claremont neighborhood Thursday alongside someone else dressed all in black who then stopped as the 15-year-old sufferer continued working.

The teen, who had been on his manner to faculty, then collapsed at East 171 Street and Third Avenue after taking a bullet to the abdomen around 9:25 a.m., according to police and regulation enforcement sources. He was initially listed in secure situation but later succumbed to his accidents.

Frimpong had lately immigrated to the US from Ghana — and was being bullied at 329 The DreamYard Preparatory School, according to his father, Thomas Frimpong, 60, who informed The Post he believes it is tied to the slaying.

The principal had called just two days before the homicide to inform Thomas Frimpong that his “very quiet” son was being bullied, he said.

“He said, two boys were fighting with my son, and the two boys got suspended,” the dad said.

He got another call Thursday — this time with even more harrowing information.

“The principal called me that my son has been shot,” he said, including that he rushed to St. Barnabas Hospital to see his boy before having to break the information to kin still in Ghana.

“I just called his mother [in Ghana] and even I can’t hear her voice, crying, crying, crying. All the family members are crying,” he said, breaking down with his own feelings.

Three males sporting all black, believed to be between 16 and 18 years previous, were noticed fleeing the scene after the burst of gunfire, cops said.

A close-by witness described seeing two males sporting all black with facemasks working in the park as she was strolling to faculty when she heard a gunshot.

“I heard like a gunshot. I’m like, ‘Am I tripping?’ It came from, like, inside the park,” 18-year-old Karolinne Guerrero said.

Guerrero said she instantly went to faculty so she wouldn’t “be involved.”

“I feel scared ’cause I live right there. I’m like, yo, I’m scared.”

A close-by neighbor who witnessed the capturing unfold from his window said two boys “ambushed” Javits.

The witness, who declined to give his identify, informed The Post two boys “ran after him, shot him, ran off into the park.”

“The boy was lying there for about a half hour before the cops came,” he said, noting that he feels actually responsible for not calling the cops but he didn’t need to jeopardize his parole. 

“People were just walking by him. Then a lady came out [of the nearby homeless shelter] and she called 911. She was frantic,” he said. 

“It’s like back in the day. Nothing ever changes. They’re still shooting each other,” the witness added.

No arrests have been made and the motive for the violence stays under investigation, cops said Friday
