So far 1,068 candidates, out of those who cleared the written examinations held last year and were to take the physical eligibility test, have been arrested over the last two weeks during the screening of their documents.
Around 52,000 candidates were selected for the screening of documents at Patliputra Sports Complex here in the state capital.
"Our officials discovered that other persons appeared in the written tests in place of the arrested candidates. This was done by transposing or morphing photographs used in the examination applications, forging signatures, using fake certificates and other papers," said Bihar Director General of Police (DGP) P K Thakur.
"The screening has just started, and we intend to complete it along with physical eligibility tests till the end of April to proceed ahead with the recruitment of constables.
