New Delhi, Sep 2 (Agencies): In the first sentencing in the 2010 Commonwealth Scam, five people have been sent to prison.

Four civic officials were sent to jail for four years and the managing director of a private firm, Sweka Power Tech Engineers, TP Singh, has been sentenced to six years by a Delhi court.

The convicts had asked for a lenient sentence arguing that they had spent around 11 months in jail during the trial.

This is the first case related to the Commonwealth scam decided by the court.

According to a CBI chargesheet in 2011, the convicts entered into a criminal conspiracy for upgrading street lights for the Commonwealth Games in October 2010 and awarded the contract to a private firm by manipulating tender documents.

This caused a loss of over Rs.1.42 crore to the government, said the CBI.

The CBI also charge-sheeted Mehul Karnik, an employee of Philips India, as an accused in the case, but he was later discharged.

Four officials of the Municipal Corporation of Delhi were held guilty of criminal conspiracy and cheating.
