A 17-year D.C. police officer was stabbed and critically wounded yesterday on the Mall after he allegedly struck a man with an umbrella during a dispute that apparently involved the officer's wife, U.S. Park Police and D.C. police said.

Charles C. Battle, 39, was stabbed in the left side of his neck and chest and his left forearm during the 1:30 p.m. incident and was flown by a Park Police helicopter to the Washington Hospital Center's MedStar unit, where he was in critical condition last night, a hospital spokeswoman said.

Battle, who lives in Fort Washington, works in the D.C. police property division in a nonpublic role, a District police spokesman said. A Park Police source said that Battle's police powers had been revoked. It was unclear last night if Battle was on duty at the time he was stabbed.

According to Inspector Jimmy Wilson, commander of the D.C. police Internal Affairs Division, Battle is under investigation by D.C. police "as a result of having been arrested on a domestic assault charge in Prince George's County."

Details of yesterday's stabbing were sketchy. Park Police Maj. Richard J. Cusick said last night that the department would not release the name of anyone involved in the incident because it was still under investigation.

No one has been charged, another Park Police official said.

The stabbing occurred on 12th Street NW north of Madison Drive, between the Smithsonian Museum of History and Technology and the Museum of Natural History, Park Police said.

Cusick said a man, identified by police sources as Battle, saw his wife with a male companion and struck the companion with an umbrella, after which the companion pulled out a knife and stabbed his attacker.

There was "no information" to suggest that the encounter was a result of a scheduled meeting among the three, Cusick said.

The man who was hit with the umbrella was taken to Georgetown University Hospital, a Park Police source said, then taken to the Park Police criminal investigations division, where he was interviewed and released.

"The victim of the assault the man attacked with an umbrella turned around and defended himself," Cusick said, explaining why no one was charged in the incident. "The original assailant Battle is apparently the more seriously injured person," he said. "The case will go to the U.S. attorney's office to consider what charges, if any, will be placed," Cusick said.
