Jamaican distance runner Kemoy Campbell was taken to the hospital on Saturday after he collapsed and stopped breathing during the men’s 3,000m at the Millrose Games in New York.

Campbell, 28, was acting as the pace-setter during the sixth lap when he fell off the banked track into the infield near where the men’s shot put competition was under way.

Spectators watching from trackside and the balcony in the southwest corner of the Armory screamed in vain for the race to stop while track officials tried to resuscitate the 2016 Olympian until the arrival of paramedics, who performed CPR and treated him with an automated external defibrillator as he lay immobile.

Once the men’s 3,000m was completed despite the chaotic scene unfolding by the second turn, the meet was suspended for about a half hour as police and EMTs continued to treat Campbell.

An eyewitness said the former University of Arkansas star, who competed in the 5,000m at the Rio Olympics and has been hailed as Jamaica’s first world-class distance runner, was breathing and showing a pulse but still unconscious when he was carried out of the arena on a stretcher and transported to NewYork-Presbyterian/Columbia University Medical Center across the street in Manhattan’s Washington Heights neighborhood.

A fire department spokesperson did not immediately provide information on Campbell’s condition, nor did competition organizers.

After the meet resumed Ethiopia’s Yomif Kejelcha won the prestigious Wanamaker Mile in 3min 48.46sec, a single one-hundredth second off the world indoor record set by Hicham El Guerrouj of Morocco in 1997.
