She's not getting anything, the costs go to the prosecution. She's a victim, she hasn't paid any fees. There won't be a civil action.
Can she sue for damages?
Not sure. I wouldn't have thought so, it's just generally not something that happens in this country. She won't anyway though.
Contrary to popular belief on Facebook, there's not big money to be made from being a victim of crime. Even if you're burgled and they catch him, you'll be lucky if he's ordered to pay back the full amount of the losses.
But according to Facebook she knew what she was doing and is going to sue him for £1million. Are you saying I shouldn't believe everything I read on Facebook?
