Very minor bike accident

Yesterday in a very busy crawling traffic, a biker came diagonally near my car's front right corner and since I was occupied in other traffic, momentarily my car kind of touched his bike (my speed was barely 1-2 kmph, slower than walking, practically almost standing). He did not fall and no injuries, but he settled down his bike on the road and charged at me with his helmet in hand as if coming to hit me. I was sitting with my wife, so when I felt nothing major has happened I slowly made my way out of traffic without getting out, but in the process, he ran at me from behind and hit my rear windshield hard with his helmet, which fortunately did not shatter, else could have been injurious to me and my wife. I could have got out to talk amicably but I did not want someone violent to charge at me with my wife sitting with me. My question is can the bike guy file any police complaint or anything which can possibly create a legal action? Although such minor incidents are extremely common on Gurgaon roads, and once or twice when I've been involved in such, I've amicably sorted them out.
