Four people, including two Bharatiya Janata Party (BJP) workers and a sub-inspector, were arrested on Monday in connection with the police constable recruitment exam paper leak, an official said. The exam was cancelled hours before it was scheduled to commence on Sunday after authorities learnt that the paper had got leaked. As many as 8.75 lakh candidates were scheduled to appear for the exam at 2,440 centres across Gujarat. Since two of the accused - Manhar Patel and Mukesh Chaudhary - were associated with the ruling BJP, the state party unit ordered their suspension with immediate effect following their arrest.
