Interpol's Most Wanted beware: your new Facebook friend might be turning you over to the authorities, if the international police organization has its way.

Interpol has launched a public appeal on social networking websites for help in the search for 26 people convicted or suspected of crimes such as murder, child sex abuse or trafficking.

The public appeal comes amid reports that an Interpol operation, dubbed Operation Infra-Red 2010, has only managed to catch or locate 107 out of 450 targets.

Of those targets, the international police organization has dubbed 26 of the fugitives as particularly dangerous, including a Canadian.

David MacDonald Carrol, a Quebec Hells Angel, is wanted in connection to up to 13 deaths.

The organization says it has failed to find any trace of Carrol, or the other 25 most dangerous suspects on the list.

Norman Inkster, a former president of Interpol, said the organization is widening its information net.

The organization's leadership "is recognizing it is time to modernize Interpol and we've seen several incidents where they are reaching out for the public's assistance," Inkster told CTV's Canada AM.

With more than 500 million Facebook users, and millions more on other social networking websites, Interpol is vastly increasing the number of potential leads.

"Law enforcement is everyone's responsibility, not just the responsibility of police officers -- they've increased their reach by a hundred-thousand fold by using Facebook," Inkster said.

Inkster said that wanted criminals put information online just like anyone else.

"It's always surprising to me how much information goes on sites like Facebook and YouTube and others," he said. "Some people think they've been out of the public eye for a few years, people have forgotten about them, they've changed the way they look and no one will recognize them.

"But that's not true."

It is the first time Interpol has asked for the public's help on such a large basis. The organization, which links police from 188 countries, generally works quietly behind the scenes.
