A new 60-second video in seven languages may "rattle" the kidnapper of missing Madeleine McCann, investigators in Britain said.

The video, called "A Minute for Madeleine," was posted to Internet sites Tuesday with a plea to spread it to news Web sites, blogs and social networks, said Jim Gamble, who heads Britain's Child Exploitation and Online Protection Center.

The video asks friends, relatives or the spouse of the person who kidnapped the girl to "do the right thing" and contact police, Gamble told The Times of London in a story published Tuesday.

Madeleine, whose family lives in England, was 3 years old when she disappeared during a family vacation in Portugal in May 2007. The new video, posted in English, Arabic, Portuguese, Spanish, French, German and Italian, shows images of how Madeleine might look today at age 6.

"It's aimed at prompting the conscience of the person who is keeping the secret" and "rattling" the kidnapper, who likely checks the Internet for developments in the case, Gamble said.
