A creeper is creeping me out, i dont know what to do about it?

Yesterday on a train a creeper started talking to me and when I was supposed to leave, he didnt let me go before me giving him my number and email. now since yesterday he has called me like 10 times. smsed once. and i have ignored it all and i am relaly afraid as i live in Sweden and there is a law in sweden that you cna find everything about a person only by typing ones name in the internet, so he knows where I live and my full name cause he knows my number. I found his name too cause I am really afraid but now i dunno what to do? help please??
