Sec 279 in a parking lot

Dear lawyers, I accidentally scrached a parked car while backing my car. There were a few negligiable scraches and a minor damage on the bumper. But the car owner demamded that I go with him to the mechanic to incurr the charges for the repairs. They were 5 people all from a nearby shop and were pressurising me. I appolagetically told the owner that he keep my visiting card or copy of DL or RC, so that I could pay him the repair bill by cheque. I was sure they were going to demand unreasonable and hefty amounts. So I called in the police in distress. Now, the police said that I should settle it with them or he would impound the cars because I would be charged under Sec 279, of IPC. CAN HE CHARGE ME WITH THIS SECTION IN THE GIVEN CIRCUMSTANCES? IS A PARKING LOT A PUBLIC ROAD AS READ IN SEC 279 IPC. CAN THE POLICR IMPOUND CARS? SHOULD THE POLICE LET ME SHARE MY CONTACT DETAILS WITH OWNERS, SO THAT I BE SUED ?
