Los Angeles police are investigating three officer-involved shootings in the last three days during which suspects were wounded or nearly wounded.

The first incident took place Sunday shortly before 11 p.m. in the 3800 block of West Jefferson Boulevard in West Adams after officers responded to a domestic dispute report and were allegedly confronted by a man with a knife, the Los Angeles Police Department said.

Gunfire ensued, police said, and the suspect was grazed in the head by a bullet.

The second incident occurred Tuesday in the 300 block of East 107th Street in Watts shortly after 8 p.m. as officers were serving a search warrant. They said they encountered a man who brandished a handgun and tried to load it.

At least one officer opened fire, hitting the man in the leg. He was taken to Harbor-UCLA Medical Center, police said.

On Wednesday evening, narcotics officers serving a search warrant in the 5700 block of Stansbury Avenue in Van Nuys were confronted by a man wielding a shotgun. At least one officer fired a weapon after the man allegedly failed to comply with commands, police said. The man was not hit in the incident, which occurred about 5:25 p.m., according to police.

No additional details were available Wednesday night.
