A D.C. police officer shot and seriously wounded a Northwest Washington man in Georgetown early yesterday in a confrontation that occurred while the officer and two others were searching for robbery suspects, D.C. police homicide detectives said.

They said Darrell L. Adgerson, of 4911 7th St. NW, was shot by Officer David M. Becton about 1:40 a.m. in the 3300 block of M Street NW.

According to a report prepared by the homicide unit, Becton and two other officers were in the 3300 block looking for robbery suspects when citizens stopped them and directed them to a man in front of the Little Tavern there.

As the officers approached the restaurant, the report said, a man began walking away rapidly. Becton walked in front of the man, and ordered him to halt, but the man kept moving.

Becton again ordered him to stop, detectives said, but the man "suddenly went into a crouch position and stuck his hand into his right pants pocket." As the man was removing his hand from his pocket Becton drew his revolver and fired one shot, which struck the man in his lower right side, the report said.

Adgerson was listed in serious and guarded condition last night at George Washington University Hospital. His age was not available. Police said no charges have been placed against him.

A woman who said she saw much of the incident told a reporter yesterday that it appeared to her that Adgerson had been involved with one or more other men in a verbal dispute involving a T-shirt shortly before the shooting.
