Prince George's County Police arrested three juveniles and two adults early yesterday when a melee erupted after a youth dance at the Seat Pleasant Recreation Center, police said.

When officers arrived at the center at 5720 Addison Rd. at 1:05 a.m., a large group of people who had been fighting ran from the building's parking lot to a service station across the street and a second fight broke out, police said. Police reported that the crowd threw rocks and bottles at officers attempting to make arrests.

The adults arrested were Gerald and Gerry Evans, both 20, of the 1300 block of Nome Street in Capital Heights. Gerald Evans was charged with assault and battery with intent to maim. His brother, Gerry, was charged with disorderly conduct and resisting arrest. They were both released on personal bond shortly after their arrest, police said.

Gerald Evans said yesterday that he and his brother did not attend the dance but had stopped at the service station for gas when they were attacked by the crowd.

After the crowd had been disbursed, an officer struck his brother from behind with a night stick, knocking him unconscious, he said. Evans said another officer slammed him against his car and placed him in handcuffs.

"We were just innocent bystanders," Evans said. "The police locked us up for simply defending ourselves."
