What's the best way to deal with a stalker?

A guy used to stalk me a few years back, but he went to prison for beating up his ex wife. He is out of prison now and back on the scene.

He was parked outside my house yetsterday and followed me to work. He's at most places I go and I can see him staring at me out the corner of my eye. I pretend I don't notice him . It's like he's letting me knows he's back again.

My husband works away and it's impossible for him to come home. I did contact the cops for advice but there isn't anything they can do. I don't even know the guys full name and I haven't actually been threatened.

What's the best way to deal with this situation without provoking the guy as he is violent?
