A 16-year-old boy has been charged after he allegedly assaulted another teen at a fast-food restaurant in Ewa Beach.

The teen was charged with third-degree assault.

Campbell High School sent a letter to parents Friday to inform them of the assault that involved students who were harassed by the suspect.

At about 4 p.m. Thursday, police and Campbell High said the students were at the fast-food restaurant when the male suspect approached them and asked for money.

When one of the students, 16, told the suspect to stop bothering them and leave, the suspect brandished a gun and struck the victim, causing injury.

Police said the suspect then fled the scene.

Shortly before 8:10 a.m. Friday, police located the suspect and arrested him on suspicion of second-degree assault.
