My creepy new coworker?

So there’s this guy was new at work my HR introduced him to me normally when someone saw you they greeted so he gives dead stares no words my HR didn’t pay attention at the end of conversation and my HR pat my shoulder l turn my back as l say don’t want talk with him. Next days l take the bus and saw someone get up their seat as soon l take seat l saw him he was infront of me so l sit in back. And when we go off on bus feel uncomfortable l make an excuse to go at convenience store so he was looking at me directly when l finished buy something he was waiting for me in bench so l decided to avoids him again. After in cafeteria he would stares at me in way very uncomfortable so l ignore him. Next day take another bus to avoids him and when l go off the bus I saw him again l was confused because he was supposed to be at work already so l lgnore him and start stalking me by pretending call someone so l stop and he decided to stop too l was full rage that I go to work l tell my HR about this situation but her advice didn’t help at all so l talk with my other coworkers l trust and she tell me isn’t normal he acts this way and tell her l’m not interested with him and l don’t want to his friends. I go to work by changing hourly and everything is fine but when l’ve to eat in cafeteria when l was alone lt made me no safe and saw him l’ve to leave the room quickly all the time. I try to avoids him and he works in office he pretends to go downstairs he can use the door to leave he was afar distance so he use the third door and he was giving pervert looks as soon l saw him it was third time he did this to me. His behaviour was strange and not friendly l don’t know why he acted suspicious
