A man who attended an all-day music festival at Merriweather Post Pavilion in Columbia, Maryland, has died from an apparent drug overdose, police said Saturday.

Howard County Police identified the deceased as 20-year-old Tyler Fox Viscardi of North Carolina. Viscardi and at least 20 others were hospitalized for possible overdoses and other drug-related effects after attending the Mad Decent Block Party Friday, The Baltimore Sun reports.

A 17-year-old male from Virginia, whose name has not been released, was among the concert-goers who were hospitalized. Officials say he is in critical condition.

Viscardi was transported to a local hospital around 9 p.m. Friday and was pronounced dead shortly thereafter. Though a drug overdose is suspected, officials have yet to confirm the cause of death. Authorities are reportedly working to determine what type of drugs were in his system.

Officials behind the record label — launched by electronic music DJ and producer Diplo — took to Twitter Saturday to address the incident.

Our hearts go out to everyone impacted by yesterday’s event. We are saddened by the news.

Aside from the hospitalizations, police made three arrests at the venue for assault on a police officer, domestic assault and possession with intent to distribute marijuana. Officers also issued 50 citations for underage drinking during the festival.

Unfortunately, substance abuse has become increasingly common at music festivals and concerts. In June, dozens of Avicii fans were hospitalized after a concert in Boston. Officials later revealed that the drug ecstasy played a major role in the hospitalizations.
