A female RCMP officer in British Columbia has launched a second lawsuit against the national police force.

Const. Karen Katz is taking the RCMP and the attorney general of Canada to court over unproven allegations of harassment, sexual harassment and humiliation dating back to the late 1980s.

Earlier this year, Katz filed a separate lawsuit against fellow officer Baldev (David) Singh Bamra and the provincial and federal governments over allegations of harassment and sexual assault.

RCMP Supt. Ray Bernoties says the force hasn't reviewed the most recent allegations, and that at some point all the facts will be known and statements will be made under oath in court.

In her most recent statement of claim, Katz alleges a superior described her as being a security risk who was infatuated with outlaw motorcycle gangs and biker men.

Katz, who is the author of four books on outlaw biker culture, alleges she has also been subjected to "offensive, humiliating and demeaning" sexual comments.

None of the allegations made in her statement of claim have been proven in court.

The RCMP is facing a raft of sexual harassment allegations from current and former female officers, including a class-action lawsuit that lawyers say could include up to 150 women who have stories of harassment and gender-based discrimination in the police force.

Confronting the emerging scandal was one of RCMP Commissioner Bob Paulson's first priorities on being sworn in late last year.
