Mumbai Traffic Police — chembur gymkhana

I am resident of subhash nagar, chembur (E). Whenever there is any event or function carried out in chembur gymkhana, all the vehicles are parked outside on the road outside infront of our society and municipal school all day long. It causes huge problem for the trespassers and school students. Buses are prohibited from that way. Even there is no way for the ambulance due to those vehicles.
Please do the needful.
