Looking for a witness to incident

There was an incident that happened Friday, June 20, in downtown Coquille. My nephew and his girlfriend walked in downtown Coquille and he was approached by a group of teenagers. One of the boys walked up to him and started pushing him around and giving him a hard time. The boy pushed my nephew in front of a moving car, but luckily he was not hurt. My nephew then walked away from this boy and the boy grabbed him by the back of the shirt. My nephew had his skateboard in his hand and in self-defense used his skateboard to protect himself. The boy put up his arms to protect himself, so he was not hurt.
