How do you report a facebook profile?

[Uzumaki]

ok one of my friends profile on facebook has been hacked, someone must of logged on to her account and the worst part is as her status it shows her house address, house number, telephone number and mobile number. this is so wrong how could facebook let something like that happen and not have report button, what should i do this is so wrong all her information is being given out, and her info says all over that she likes porn. this is so wrong!
