A 16-year-old boy was arrested in connection with the robbery of another teenager in the Halawa area Wednesday morning.
Police said the suspect approached the victim, 15, from behind as another male, who has not yet been located, threatened him with a knife.
The suspects took a cellular phone, an iPad and his bus pass. The first suspect also threatened to kill the victim if he told anyone about the incident.
The suspect was identified, located and arrested on suspicion of robbery Friday night.
