A female pedestrian was critically injured Wednesday morning in Kalihi when she was struck by a sedan driven by a police officer going to work, police said.

Police Lt. Robert Towne said the accident took place on North School Street, at the intersection of Pohaku Street, at 5:27 a.m.

A 49-year-old woman was crossing School Street toward the makai side when she was hit by a Nissan sedan driven by a police sergeant on his way to work, Towne said. The car was traveling east on School Street, Towne said.

The woman was in a crosswalk, a witness told police. The woman ended up about 25 feet from the crosswalk, Towne said.

The witness said the pedestrian was dressed in dark clothing and that a street light above the crosswalk was out.

Police said the witness reported that it appeared the pedestrian was hurrying across the four-lane road with her attention on an approaching mo-ped.

Officers closed School Street for about three hours to investigate.

Towne said it did not appear that speeding or alcohol were involved. Police said the road was wet.

Police said the officer assigned to the Kalihi District is 48 years old and a 21-year veteran. He took a required blood test.

Police will turn the case over to police Professional Standards Office as standard procedure.
