A young man died at the HARD Summer festival downtown last night, a police official told LA Weekly.

An overdose was suspected, the official said. It appeared to have happened in front of fellow concertgoers at Los Angeles State Historic Park. Artist Flying Lotus, who was scheduled to go on at 10:25 p.m., tweeted this:

Flying Lotus performed on the Harder Stage, across from the main stage.

She told the Weekly the victim was “reported to be in cardiac arrest:”

A 25-year-old male was found unresponsive, pulseless and non-breathing at the venue by a team of veteran LAFD paramedics. He was transported in grave condition to L.A. County-USC Medical Center.

A spokeswoman for the hospital told us she couldn't release any information without the victim's name. A coroner's official said the case “has not been reported to us yet” and that she had no documentation on it this afternoon.
