Rocker Courtney Love has launched a scathing attack on her bank manager, branding her a “cheating lying thief.” Love claims around $20 million has disappeared from her account in the last four years, and also holds her bank manager accountable for her sister-in-law, Kim Cobain, having her house repossessed.

The case is currently being investigated by the FBI.

Love wrote on her blog on Thursday, “Man do I have a cheating lying thief of a banker. All I’ll say is she knew these accounts in 2003 were forged and she went along with 4 refinances in one day of Kim Cobains wich (sic) ended up with them taking her home from her while she did what? Got bigger, fatter greddier (sic) more rapacious?…Bitch. I don’t think a day a week devoted to the maintenance of my income and my daughter’s is too much to ask – its a moneypit to keep paying forensics. (It) makes me truly sick, one thinks ‘oh a banker won’t steal from me’ – think a bloody gain.”
