A 17-year-old boy was arrested Monday after a 13-year-old girl told authorities the boy sexually assaulted her late Friday evening in the Makalapa area.

The girl said the boy, whom she described as an acquaintance, assaulted her about 10:30 p.m. Friday.

Police found the boy Monday and charged him with two counts of first-degree sexual assault and two counts of third-degree sexual assault.

Police said the case has been turned over to Family Court.
