A woman was stabbed in the popular U Street corridor in Northwest Washington early Sunday, D.C. police said.

The stabbing is one of several overnight incidents under investigation by D.C. police. Another stabbing was reported around 2 a.m. Sunday in Southeast Washington. Police also are investigating a Saturday night carjacking in Northeast and several overnight robberies across the city.

In the U Street N.W. incident, police said, an altercation between two women originated inside a nightclub and continued outside the establishment. One of the women allegedly stabbed the other around 2:50 a.m., in the 1300 block of U Street NW.

The case remains under investigation, D.C. Police Officer Paul Metcalf said. Authorities did not release details about the severity of the stab wounds, but said the victim was taken to a local hospital.

At 2 a.m., D.C. authorities were called to the 4600 block of Livingston Road SE, where they found two men suffering from stab wounds. Police said a woman was arrested and charged in the incident.

The victims were taken to area hospitals, police said. It was unclear what led to the assault, police said.

Police Sunday said they were on the lookout for two suspects in a carjacking at 5000 J Street NE, around 8:45 p.m. Saturday. Police said three men approached a victim at the location, one of the man displayed a handgun, and the men fled in the victim’s vehicle.

One of the suspects was arrested following the incident and two remained at large as of Sunday morning, police said.

Authorities also are investigating several overnight robberies in the city, including three that took place within a one-mile radius in the Petworth-Columbia Heights neighborhoods in Northwest.

Police said there is no indication of a connection in the incidents. Police made an arrest in one of the cases and continue to investigate the other two.
