Both Fox5 and NBC4 are reporting the incident:
D.C. police said they are investigating a shooting involving an officer.
Sources told News4 the officer suffered a graze wound to his face in the 700 block of Irving Street in Northeast. There was no word on what the officer was doing when the shooting occurred.
A priest told News4 that he heard three shots and saw the officer on the ground when he went outside. The priest said he was surprised the wound wasn't more serious because it was a close-range shooting.
Police said the gunman was a black man standing 6 feet 5 inches tall, weighing 200 pounds, wearing blue jeans and carrying a black backpack.
The man fled down Eighth Street and was last seen running toward the Brookland Metro Station, police said. Trains were stopped as officers from D.C. police and Metro Transit Police searched the station and tracks for the shooter.
The officer was taken to an area hospital for treatment.
More from WTOP:
An intensive manhunt is underway after a D.C. Police detective was shot in a neighborhood near Catholic University, D.C. Police say.
D.C. Police say the detective was grazed on the side of his face by a bullet after a man opened fire around 1:20 p.m. Friday.
The shooting occurred in the 3100 block of 7th Street in Northeast, near Catholic and Trinity universities.
The detective is a member of the Capitol Area Regional Fugitive Task Force, a U.S. marshal-led task force.
The task force was in the area serving arrest warrants, but it's not clear whether the shooter was wanted by police or just opened fire when he saw the officers.
The suspect is still on the loose and considered armed and dangerous.
He is described as a light complexioned black man, about 36 years old with light facial hair. He is 5 feet, 8 inches tall, and weighs about 160 pounds and was carrying a black backpack.
Police say the detective is expected to be released from the hospital later Friday.
The suspect was last seen fleeing on the railroad tracks east of Catholic University, according to a message on Catholic University's Web site.
Earlier, Catholic University students in the Spellman and Conaty residence halls - the buildings closest to the shooting - were informed to stay in their buildings, but the alert has been lifted.
The university is not on lockdown and there is no evidence to suggest the gunman is anywhere near campus.
