Two teens who watched their buddy attack a Columbia University graduate student will not be charged in the talented scholar's death, cops said Sunday.
After studying surveillance tape and interviewing the two teens, detectives determined only one of the trio punched Minghui Yu - who ran into Broadway to escape the attack and was struck and killed by a southbound Jeep Cherokee.
"We saw that it was only the actions of one of the kids that sent the victim into his flight," a police source said.
A 14-year-old Bronx boy was arrested Saturday and charged with manslaughter. Police said he punched Yu, 24, repeatedly at Broadway, near W.122nd St., as Yu walked back to the Morningside Heights campus at 8:50 p.m. Friday. The student was headed home after dinner with his girlfriend, classmates said.
Cops have not released the suspect's name because of his age.
"It's a mistake. That's it," the boy's aunt said as cops hauled him to a juvenile detention facility early Sunday.
