The body of a 17-year-old boy was found late Tuesday night in a stream behind a Taco Bell on Farrington Highway in Waianae, police said Wednesday.

The teen may have fallen down a 15-foot concrete embankment into Kaupuni Stream behind the fast-food restaurant at 85-752 Farrington Highway about 10:10 p.m., according to police.

The boy was identified as Brian Reian of Waianae, said the city medical examiner’s office.

Police said they do not suspect foul play and that alcohol may have been a factor in his death. An autopsy is scheduled later today.
