Internet experts are warning young Justin Bieber fans to be extra vigilant after web fraudsters set up a scam enticing the singer's devotees with the lure of free gig tickets.
The Baby hitmaker is known for his strong online following and regularly keeps in touch with his loyal fans using social networking sites Twitter and Facebook.
But a new scheme is targeting Bieber's Facebook friends with a link to a bogus free ticket giveaway for the star's ongoing U.S. tour, with the words, "Wow! Justin Bieber is giving away free tickets now".
Experts are concerned many youngsters will be tricked into clicking on the link, which snares them into an online fraud, and they are urging Bieber fans to take care.
A statement form online security firm Sophos reads, "This is a dirty rotten trick on youngsters."
