The state government has initiated yet another investigation against controversial IPS officer Param Bir Singh for using an official vehicle, with a red beacon, without taking charge and reporting to the home department as well as the Director-General of Maharashtra Police. Sources said Singh, who faces multiple FIRs, has been visiting places to record his statements in the vehicle. 

State Home Minister Dilip Walse Patil said on Tuesday that they would probe how he was allowed to use the official vehicle while going to record his statements to places where he has been named as an accused.
