As 1010 WINS’ Roger Stern reported, the teen began handing her clothes to bystanders, left her identification on a rock, and began wading into the Hudson River.

Adeoye, of the Bronx, was caught using her cell phone during a test at school, CBS 2 reported.

A classmate said the teacher yelled at Adeoye, who then apologized.

Investigators said she then wrote a suicide note and asked to go to the bathroom.

But instead, she walked to the Hudson River’s edge at West 165th Street and jumped in, CBS 2 reported.

Witnesses pleaded with the teen to come out of the water. She did not, and eventually disappeared, Stern reported.

“She’s a very bright young lady who has a lot of hopes, a lot of vision in life. She wanted to become a medical doctor,” said family friend Godspower Izghe.

The Department of Education is launching an investigation into the incident.

The schools chancellor is promising a new look at student mental health awareness.
