thanks for the advice, my fiance has a few cousins in the police force so he called them yesterday and asked what he should do, they both said to go to doctors asap and get the injuries in your medical file, incase they try it again, rung emergency doctor and he told us to go to minor injury unit which we did and he has a badly swollen and bruised nose, they also dont do x rays on nose injuries unless it feels like your eye sockets/ cheekbones have moved place which the doctor didnt think so.
she is a total nutter and my fiance's cousin thinks if she tries it again because of the injuries that were sustained to my fiance they will think she is reporting it to cover her back which is the only reason she did it in the first place as she was scared he'd report it, what a waste of police time
