Police arrested a 25-year-old Mililani man shortly before 5 p.m. in the hit-and-run accident that killed an 18-year-old Hawaii Pacific University student.

The man was booked at the Wahiawa police station on suspicion of first-degree negligent homicide and fleeing the scene of an accident.

A white sport utility vehicle believed to be involved in the incident has also been recovered.

The bicyclist, Zachary Manago, was hit from behind on Kamehameha Highway while approaching Leilehua Golf Course 11:10 p.m. Friday, police said.

Police said Manago had been heading north along the shoulder of the highway half a mile south of the Leilehua Golf Course Road.

Manago was taken to Wahiawa General Hospital where he was pronounced dead.

Manago was with a group of 30 to 40 cyclists on a night ride that was to culminate with a view of the sunrise at Sandy Beach Saturday  morning.

Manago had lights and was wearing a helmet.

Members of the baseball and bicycling communities are mourning the loss of Manago, the ace of the Moanalua High School baseball team the past two years and a bright prospect for the HPU baseball team, which was is scheduled to begin practice in a few weeks.

"He was an exceptional athlete who took care of business on and off the field," said Scott Yamada, Moanalua’s coach, who made Manago one of two team captains last year. "As a teammate, everybody loved him. He had no enemies."

Yamada said that when Manago started at HPU, he began riding his bicycle to school because of the lack of parking on the downtown campus. That’s when he became active with the biking community.

Manago’s death was the 62nd on Oahu roads this year, surpassing the 55 in all of 2009.
