NEWS BRIEF: The 15-year-old student who brought a gun to Berkeley High on Jan. 10 was arrested last night in connection with a robbery at Shattuck and Kittredge around 10 p.m. The young man and two other suspects, all under 18, fled the scene of the robbery on foot as the police attempted to detain them. All were caught and arrested. In addition to last night’s robbery, there was a warrant for the 15-year-old, because of the gun as well as an amount of marijuana consistent with dealing at BHS. In the incident on Jan. 10, although the gun was secured by the police school safety officers, the student ran away.
