Coimbatore: The city police conducted a test for 33 sub-inspectors at the police commissionerate on Saturday to measure investigation process effectiveness. Assistant commissioners of police, inspectors of police and resource persons had recently conducted legal classes for 64 directly-recruited SIs here in two phases. “They were taught about their role and powers explained in the Criminal Procedure Code (CrPC),” a police officer said. On Saturday, details of a murder case were given to the 33 SIs, who attended the first phase legal classes and were told to prepare case diary, register FIR and record statements from accused and witnesses. Senior officers will evaluate their performance. Such classes and tests will improve the efficiency of investigation officers, said city police commissioner Deepak M Damor. Additional deputy commissioner Silambarasan said that the city police have been conducting classes for the last one month. “As many as 609 cops from city police stations and special units and 240 from city armed reserve police were trained. All cops in the city will get the basic training within four months,” he said. “Armed reserve police personnel were taught to handle weapons and to escort prisoners. Police personnel attending court duty were trained to maintain court case diaries and how to produce witnesses on time. Those conducting patrol were trained how to conduct vehicle checks and handle civilians,” Silambarasan added.
