Newport Beach police said they turned over several electronic devices, including a cellphone and other items taken while executing a search warrant at the home of Timothy Lance Lai.
Police said Lai, 28, was tutoring a dozen students at Corona del Mar High School when he allegedly provided them with keystroke logging devices the students implanted on teachers' computers. The students allegedly used the devices to gain access to tests before they were given and fix grades after teachers had entered them in the system, the Daily Pilot of Costa Mesa, Calif., reported Monday..
Eleven students have been expelled for their roles and some 52,000 grades are under review for accuracy, the newspaper said.
No charges have been filed against Lai though police said they will turn over the results of their investigation to the district attorney, who will make that determination.
Lai is wanted for questioning in the case but has yet to be located.
