One dead, three critical after suspected drug overdoses at Knockout Games of

A teenager has died and three other people are in a critical condition in hospital from suspected drug overdoses at a music festival in Sydney’s inner west.

Police say the 19-year-old man died in Concord Hospital after attending Knockout Games of Destiny — billed as the biggest indoor festival in the southern hemisphere — at Sydney Olympic Park yesterday.

Two women, aged 19 and 25, and a man were taken to Westmead Hospital, where they remain in a critical but stable condition.

Thirteen other people were also taken to hospital for treatment.

Officers said an 18-year-old girl was allegedly found with almost 400 MDMA caps and was charged with supplying a prohibited drug.

Four other people were also charged with drug supply offences.

NSW Police will address the media about the suspected drug overdoses at midday.

More to come.
