They confronted the man who then took off on foot. At the southeast corner of Vermont Avenue and Sunset Boulevard, police say that the suspect turned and attacked one of the officers.
"At some point on the foot pursuit we think the suspect turned and confronted one of the officers and struck the officer in the head several times. We believe at this point he hit him with a knife," said Dep. Sergio Diaz.
The LAPD says that the officer drew his weapon and fired several shots, striking the apparent robbery suspect once.
"The suspect ran across the street and collapsed. He was taken into custody on the westside of Vermont," said Dep. Sergio Diaz.
The wounded man was taken to a local hospital.
Investigators say one of the officers stray bullets apparently struck a Metro bus that was parked only a few feet away. One of the people inside the bus was injured.
"We do not know whether that passenger was struck with the officers bullet or glass fragments, but a person was slightly injured," said Dep. Diaz.
The passenger of the bus was treated at the scene, but not hospitalized.
The officer was hospitalized with bumps to his forehead.
