A Quebec man facing charges of making online threats to kill women has been denied bail after a judge described him as a "time bomb."

Jean-Claude Rochefort will remain in custody until mid-February pending his trial on charges of uttering online death threats against women.

The 61-year-old Montreal man has been in custody since December, after authorities arrested him following repeated warnings to stop posting contentious messages on his blog.

During Rochefort's bail hearing Thursday, Judge Claude Leblond described him as a "time bomb" who demonstrates a visceral hatred of women.

The public would lose confidence in the justice system if he were granted freedom before his trial, the judge added.

Rochefort's blog, described by observers as anti-feminist, paid homage to Marc Lépine, the gunman who murdered 14 women at Montreal's École Polytechnique in 1989.

Forensic psychiatrists have declared Rochefort of sound mind and fit to stand trial. He is due back in court on Feb. 16.
