If someone is chasing with bad intention

I attended my court date at a town R. Respondent was absent. After doing work in court, I was sitting with advocate in advocate room. I noticed brother of respondent gazing me and talking on phone. After a while he was joined by his friend. I took leave from advocate and started for return journey. I was using taxi car. In the way I noticed, he was chasing our car. As we turned on a usual link road, he crossed our car and came ahead of us. There exists a Bike shop of his another brother on this link road. I suspected some thing wrong and stopped car, My driver turned back. We then changed our route and reached the main road towards my city. There again he and his friends were standing near a shop on main crossing and gazing our car. Should I report this to police.
