The state police's Special Task Force (STF) arrested ATS Technology company's manager Harshit Shrivastava here yesterday.
STF sources said Shrivastava allegedly took money from candidates for increasing their marks in the marksheets.
ATS Technology had been entrusted with the task of preparing results for the Sanskrit Board examinations.
There were irregularities found in the examinations, held from 2010 to 2012.
Shrivastava will be produced in the court later in the day when STF will seek his remand for further questioning.
