AceShowbiz - Slash's estranged wife has filed court papers demanding information from the rocker's Internet service providers in a bid to identify an online troll.
Perla Ferrar claims she has been bombarded with nasty messages from another Instagram user, who has accused her of being an "unfit mother and child abuser", with the posts also reportedly referencing private information about her family, including the whereabouts of the former couple's two kids.
According to documents obtained by TMZ.com, she believes the culprit is someone close to Slash, real name Saul Hudson, and suggests it may even be the guitar great's new girlfriend.
Slash's ex, also known by her married name of Perla Hudson, explains she tried to seek the musician's help in tracking down the person behind the account, set up under the name "altperlafhudson", but he soon quit co-operating when it allegedly became clear the suspect was someone "with private direct access to the Hudson family".
Perla explains the rude posts were deleted from Instagram shortly after she reached out to Slash.
She is now asking a judge to order officials at Slash's Internet provider to disclose IP address information related to the account in an effort to help her get to the bottom of the case.
Slash filed for divorce from Perla in 2014, and was recently said to have offered to hand over $6.6 million (£5 million) in the hopes of finalising the legal aspect of their split.
