UNIONDALE - Nassau County police are increasing their patrols around two Uniondale high schools after several students were robbed nearby earlier this week. Authorities say five students had their cell phones stolen near Kellenberg High School on Wednesday, and that another student had his iPad stolen yesterday near Uniondale High School. They say the incidents happened after the schools had let out.

Police say the suspects apparently work in a pack and targeted students walking alone. They say one of the victims was even pushed to ground. Parents say they are advising their children to walk in groups and remain vigilant. Anyone with information is urged to call Crime Stoppers at 1-800-244-TIPS.
