Two Prince George's County police officers were shot in separate incidents late Tuesday night and early yesterday outside the Seat Pleasant station, a police spokesman said.

Police searched for one unidentified male suspect in the first shooting incident and for two unidentified male suspects in the second. Police are uncertain whether the two attacks were related, said spokesman Arthur DiGennaro.

Lt. Michael Mulligan, an 11-year department veteran, was shot once in the neck by a pellet gun but was not seriously injured, DiGennaro said. The incident occurred about 11 p.m. Tuesday night, he said, while Mulligan was standing in a parking lot next to the police communications center.

At 1:15 a.m. yesterday morning Cpt. Russell Van Splinter, a 15-year veteran, was shot once through the left arm and once in the chin outside the same police communications center in Seat Pleasant. He was in "fair to good condition" at Prince George's General Hospital in Cheverly, police said.

Van Splinter was parking his car behind the communications center when he "happened onto the scene and spotted two men," DiGennaro said, one of whom was pointing a long-barrelled gun, possibly a rifle, at the door.

When he got out of his car, both men started shooting at him, police said, and he returned fire. It is unknown whether he hit either of the two fleeing suspects, police said.

The Prince George's Fraternal Order of Police, Lodge 89, is offering a $1,000 reward for information leading to the arrest and conviction of the two suspects in the early morning shooting incident.
