Legal options??

My best mate is being bombarded wi' texts frae a wee guy who she met only a couple o' times. She can get up to seventy texts per day. This eejit says he loves her and cannot live withoot her. He's already hud a garden shed delivered tae her and numerous flowers. She has tried tae be nice and told him that she izznae interested. It's now gettin' quite scary. Does she huv any legal stuff that she can do tae get rid o' this freak?? The police huv already spoken tae him, half an hour later, he wiz back Textin' !!! Cheers fur any advice..
