Former Danzig Bassist Jerry Montano -- I Need Protection from My Hookup Gone Wrong

Meeting a chick on Facebook sounds good in theory ... but former Danzig bassist Jerry Montano says his experience left him with a series of harassing calls and messages ... and a trashed apartment.

According to papers filed in Los Angeles Superior Court, Montano says he was introduced to Priscilla Caputo through friends and they spoke on Facebook. He claims he met Caputo on December 5 when "she came to my place around 4 AM and stayed the night."

Montano says Caputo spent another night at his house on December 11. Two days later, Montano claims he turned down Caputo's offer to hang out again ... which he says caused her to "freak out."

Montano claims she sent him harassing texts all night and eventually showed up at his place -- when he wasn't there -- and after one of his roommates let her in, Montano claims she kicked in his bedroom door and "trashed the place."

Montano says he filed a police report and when he told Caputo about it, he claims she replied by saying if he filed charges against her, she would tell the cops he raped her.

A few days later, after he claims he received even more harassing messages, Montano requested and received a restraining order against Caputo ... ordering her to stay 100 yards away from him and his roommates.
