(Reuters) -- Seven people were arrested Sunday at the Made in America music festival in downtown Los Angeles, following an opening day that left more than two dozen people in handcuffs, police said.

During the show at Grand Park Sunday, there were four felony arrests, including one for battery and the rest for possession of narcotics, as well as three misdemeanor arrests, including one for public drunkenness, the Los Angeles Police Department said. Another 23 people were given alcohol citations, the LAPD said.

The previous day, 29 people were arrested, 23 for misdemeanors, most of them involving infractions related to alcohol, the LAPD said.

The two-day festival’s Philadelphia edition was briefly halted Sunday by driving rain, organizers said. In Los Angeles, authorities were asking concertgoers to stay hydrated amid extremely warm temperatures.

Sunday’s full day of events in Los Angeles included top-billed stars John Mayer and Kanye West.
