Four people were arrested and one, a juvenile, was slightly injured when police and residents of a Northeast neighborhood scuffled yesterday during a family argument, D.C. police said.

They said officers Kenneth Simons and Michael Wells, investigating a reported domestic feud at 239 12th Pl. NE, ran into opposition from residents of the address.

The residents and neighbors, standing in the street and sidewalk in the midmorning heat, argued that police shouldn't interfere and, during an ensuing scuffle, a 16-year-old girl was struck on the head, police said. She was treated and released at D.C. General Hospital.

The girl was charged with disorderly conduct under juvenile proceedings, and three adults who lived at the 12th Place address were arrested on the same charged. They were identified by police as Rae Pigford, 32; Patricia Dorn, 31, and Sheila Barnes, 27.

During processing at Fifth District headquarters, New York Avenue and Bladensburg Road, about 10 people from the neighborhood arrived at the station and protested the arrests, police said.

The arrested posted $10 collateral and were released. The charge is a midemeanor.

Police said that they are investigating the incident to determine if the arrests were necessary andthe force was justified.
