Police responded to a report of domestic violence at the Alexandria home of Rep. James P. Moran Jr. (D-Va.) and his wife, Mary Moran, yesterday but left without making an arrest.

Moran, 54, a five-term congressman representing Alexandria, Arlington and parts of Fairfax County, released a statement through his chief of staff that said the police call arose after a "domestic argument."

"No charges were filed. It's our understanding that the matter is closed. We hope folks will respect the Morans' privacy during this tough time," Chief of Staff Paul Reagan said without elaborating.

Neither Moran nor his wife returned a telephone call to their home for comment. Reagan said the congressman, a former Alexandria mayor who serves on the House Appropriations and Budget committees, was spending the evening at a baseball game with his 9-year-old son, Patrick.

The couple also has a 7-year-old daughter, Dorothy, who has successfully battled brain and spinal cancer since 1994. Rep. Moran also has two adult children from a previous marriage.

Alexandria police said they were called to the home at 7:20 a.m. They released a statement saying: "We conducted an investigation into the matter, however no arrests were made. It is the policy of this department whenever legally possible to arrest persons responsible for crimes in domestic situations and to refer victims of domestic violence to professional agencies for counselling."

The statement, issued in response to media inquiries, did not identify the Morans by name, and Lt. John Crawford cited an agency policy to withhold the names of "potential victims or suspects" when an arrest warrant has not been issued.
