Four people were cut with a knife and another person was shot around 1 a.m. Tuesday in two separate incidents in Northeast D.C.

In the 300 block of 51st Street NE, a man apparently cut his wife and three other people with a knife, police spokesman Officer Anthony Clay said.

The wife and another victim, a man, refused treatment, Clay said. Two of the victims, a man and a woman, were taken to a hospital with non-life threatening injuries.

The husband was arrested, but his name was not available Tuesday morning.

Around the same time, a man was shot at 19th and Gales streets in Northeast Washington, Clay said.

The man told police that he was shot in the back by an unknown person. The victim was taken to a hospital, and Clay said that he did not know the victim's condition.
