According to Officer Rodney Brown, five law enforcement officers, three K-9s and school administrators spent about an hour conducting a search at NPHS on Tuesday.
Brown said the event was pre-planned, and the school was placed in lockdown during the search.
K-9s provided by the Broken Bow Police Department, Lincoln County Sheriff’s Office and Cheyenne County Sheriff’s Office sniffed approximately 1,200 lockers and just under 500 parking stalls.
Brown said the dogs alerted on nine lockers and seven vehicles.
While no contraband was found inside the building, Brown said two students, 18-year-old Karina Wright and a 17-year-old male juvenile, were both cited for possession of marijuana and possession of drug paraphernalia following vehicle searches.
North Platte Public Schools policy states that students should have no expectation of privacy regarding items left on or in school property.
A similar search was conducted at Adams Middle School last month, but no contraband was recovered.
