Question papers of two subjects of the SSC (Class X) exam conducted by the Maharashtra State Board were found leaked at Bhiwandi in Thane district of Maharashtra on Wednesday, police said.
A case was registered at Narpoli police station against an unidentified person in this connection.
"As per the complaint filed by a state board official, examination of history and political science subjects was scheduled to take place on Wednesday," senior inspector M B Shinde of Narpoli police station said on Thursday.
"For the exam that was to start at 11 am, students were expected to be in the exam hall by 10.15 am. However, outside an exam centre at Kalher in Bhiwandi, the board official found some girl students checking their mobile phones inside an autorickshaw," he added.
