Mat Rempit aggressive attack on civilians

i was with my girlfriend driving along Jln Bt Ferringghidown to Gurney when we saw a large group of people believed to be Mat Rempit in the middle of the road. They look like they were beating up someone. So I ask my girlfriend to slow down the car and drive slowly and carefully across the group minding our own business when suddenly the group turned towards our car and attack us. They were using helmets and sticks to smash our car and tried to pull me out of my car. My girlfriend panicked and sped off from the scene.My Car windscreen was smashed and the car suffered dents all over. We went to report the incident he next day and we found out that there was another victim who was very badly injured was still in the hospital.
