Two police officers were killed and one gravely injured in two separate accidents yesterday.


Driver Kim Hoyoung, 32, and Edwin Paulino, 25, officers at a Harlem precinct, were pinned inside the Nissan Altima that slammed into a guardrail on the Bronx River Parkway and overturned near the 233rd Street exit around 6:30 a.m.


A police source said the cause of the single-car accident, which killed the two men and injured four women in the car, was “leaning toward” distracted driving, or “driver inattention.” The women, who ranged in age from 20 to 27, were in serious but stable condition at Jacobi Hospital, police said.


Earlier yesterday morning, Carlos Olmedo, 31, was rushed to Brooklyn’s Lutheran Medical Center to undergo surgery to reduce pressure on his brain after being struck by a motorcyclist at 20th Avenue and 84th Street in Bensonhurst.


Olmedo, a father of three who’s been on the force nearly four years, saw four suspected car thieves around 1 a.m. When three of them bolted from the car, he chased after, reportedly running into the road and yelling at them to stop.

No charges are pending against the motorcyclist, who was hospitalized in stable condition. The three suspected car thieves were being questioned at Olmedo’s 62nd Precinct.
