Police say a second person has died after apparently overdosing during a recent concert in Maryland.

Police said in a statement Sunday that a 17-year-old male from Woodbridge, northern Virginia, became the second person to die of a suspected overdose following Friday's "Mad Decent Block Party" music festival at Merriweather Post Pavilion in Columbia.

The Howard County police statement, released online, said the teen's name was being withheld at the family's request.

Authorities said about 20 people were taken to hospital late Friday, many with drug-related symptoms.

A post on the Mad Decent Block Party's website acknowledged the deaths.

"We were shocked and saddened when we heard the news from yesterday's event at Merriweather Post Pavillion [sic] in Maryland," the statement read. "Our hearts go out to everyone impacted by this. Right now, we are waiting along with everyone else for more information."

Police say 20-year-old Tyler Fox Viscardi of Raleigh, North Carolina, was pronounced dead at a hospital Friday. Police say it doesn't appear the men knew each other.

Police have said they are awaiting toxicology results in the deaths.
