There was an Indian man and his friend around our neighborhood that I suspect is faking car accident to rob people. He would drive his motorbike when a car comes and pretend as if the car hit his motorbike. I had seen this happen twice and it was the same Indian man who tried to get his oil tank filled at the petrol station without paying. He would go to the counter and ask them to let him fill the tank. But when the cashier ask for receipt, he can't show it and the cashier shout at him and then they started to argue. The other day, there was also a kidnapping done by Indian at the primary school. They grabbed the boy into the car but the boy bite the kidnapper's hand and open the car's door to jump out.
Sounds like you need to alert your local police. Make sure you emphasise that there is a bad person before you focus on his race.
