Two D.C. police officers were shot and wounded last night in separate incidents, one of them apparently an accident, and the other apparently the result of a misunderstanding.

In the shooting that appeared to stem from a misunderstanding at a delicatessen in Northwest Washington, police arrested the store operator and charged him with assault with a dangerous weapon.

Officer Martin Manfredi, of the 4th District, and his partner, went to Knight's Delicatessen, at 221 Upshur St. NW, about 11 p.m. in response to a call about disorderly persons.

After finding the store closed the officers checked the door. As they were returning to their patrol car, a shot rang out, and officer Manfredi was struck in the left thigh.

Manfredi was taken to the Washington Hospital Center, where he was reported in good condition early today.

Shortly after the shooting, police said they arrested Hermonth Shiimi and charged him in the incident. Investigators said they found a bullet hole in a wood panel at the store indicating that a shot had been fired from within with a small caliber weapon.

According to one police account, the store owner said he had been harassed by juveniles earlier yesterday, and may have believed the youths had returned and were rattling his door. Police said they had received at least three complaint calls from the store before the shooting incident.

No arrets were made in connection with any of the disorderly conduct complaints, police said.

In the other shooting incident, an off-duty officer attached to the 6th District was shot in the chest and seriously wounded in what was described as an accident in a liquor store in Seat Pleasant.

Officer Emmett Gordon, 30, a 10-year veteran, was in the back room of Pleasant Liquors, 5704 George Palmer Hwy., about 10:30 p.m. with a friend, who works at the store, when the shooting occured.

Authorities said the friend, identified as Stephen Granville, was cleaning Gordon's gun when it accidentally discharged. Gordon was undergoing surgery early today at Prince George's General Hospital.
