Montreal police are investigating a website that lists the names, addresses and phone numbers of black people suspected of criminal behaviour.

Among the names on the site are those of the men charged in an alleged gang rape in north-end Montreal last month.

The Centre for Research-Action on Race Relations has filed a complaint about the website with the Canadian Human Rights Commission. Centre spokesman Fo Niemi said the website incites violence against black people.

"We have to think about the family of these men who have been charged, or even arrested, because if those addresses are those of the families, then certainly those families are at risk," he said.

Niemi says he's worried that the site could provoke mob justice, and jeopardize the gang-rape suspects' rights to due process.

Police spokesman Rafaël Bergeron told CBC News that investigators are now trying to determine if posting the names constitutes a hate crime.

In the alleged gang rape, five men face charges ranging from armed sexual assault to forcible confinement after a 21-year-old woman claimed she was sexually assaulted by 13 men in north-end Montreal last month.
