A 21-year-old man linked to three reported incidents of indecent exposure on the University of Hawaii campus has been charged with three counts of misdemeanor sexual assault.

Police said Caleb Hopkins was arrested and charged Wednesday with three counts of fourth-degree sexual assault. He is free after posting bail of $3,000. He was arrested on Ala Moana Boulevard near the Ala Wai Canal.

The first incident was reported Nov. 3 after a student saw a man fondling himself near the physical education and athletics complex on the lower campus at about 8:40 a.m. Another indecent-exposure incident was reported at 4:10 p.m. Nov. 19 near the Clarence T.C. Ching Field on the lower campus, and a third took place Saturday on the lower campus.

A photo taken Saturday, and released by UH-Manoa campus security, shows a man with a beard and wearing sunglasses.
