Three teenage boys were arrested for allegedly beating and robbing a 17-year-old boy at a bus stop Saturday night in Waipahu.

The victim was sitting at a bus stop at 11:40 p.m. when four boys approached him and demanded money, police said.

He said he had nothing to give them and they began to kick and punch him, then took his cap and shoes, police said.

Officers located and arrested three of the attackers. The other boy remained at large yesterday.

The victim declined medical treatment.
