A 29-year-old man was fatally shot in Northeast D.C. in one of several violent incidents that occurred Sunday night and early Monday morning, police said.

About 6:40 p.m. Sunday, police went to the 4100 block of 20th Street Northeast for the report of an unconscious person inside a vehicle. When officers arrived at the scene, they found Frederick Booker, of Northeast D.C., suffering from a gunshot wound, police said.

Booker was taken to a hospital, where he was pronounced dead, police said. No information about the suspect was immediately available.

The homicide was not the only violent incident that occurred over the night. In separate incidents, three other people were stabbed and a fourth was cut.

• About 6:55 p.m. Sunday, a man was punched and stabbed with a knife in the 400 block of Second Street Northwest after being approached from behind. He was taken to a hospital, and police did not have any description of the assailants, police spokeswoman Officer Tisha Gant said.

• At about 8:30 p.m., a man was approached by four males in the 2200 block of 15th Street Northeast. The assailants assaulted the victim and cut him with an unknown object, Gant said. The victim was taken to a hospital.

• At around 11:15 p.m., a woman was exiting a vehicle in the 400 block of Emerson Street Northwest when she was approached by a man and stabbed, Gant said. The woman was taken to a hospital, Gant said. Police are looking for a black man about 6-foot-1, with a thin build and curly afro. He was wearing a black and white track suit.

• Shortly before 2 a.m. Monday, a man was stabbed in the chest and arm in or near Fur Nightclub, which is at 33 Patterson Street NE. The man was taken to a hospital. Police did not have any suspect description in connection with this incident, Gant said.

The nightclub is near where 13 people were injured during a drive-by shooting in March. But police spokeswoman Saray Leon said that she did not know if Monday's stabbing was related to that earlier incident.
