A 16-year-old boy was killed this morning after he reportedly jumped in front of an "A" train at the 42nd Street station.

The NYPD says the train operator of a southbound A train observed the young man, who appeared to be "emotionally disturbed," jump in front of the train as it entered the station at around 8 a.m. this morning. He was declared dead at the scene, and investigators believe he was not the victim of a crime.

Though an NYPD spokesperson was unable to confirm the victim's age, DNAinfo reports he was 16 years old.

The incident temporarily snarled service on the A, C, and E lines during this morning's rush hour. Service has since resumed with heavy residual delays.

If someone you know exhibits warning signs of suicide: do not leave the person alone; remove any firearms, alcohol, drugs or sharp objects that could be used in a suicide attempt; and call the U.S. National Suicide Prevention Lifeline at 800-273-TALK (8255) or take the person to an emergency room or seek help from a medical or mental health professional.
