Police officials say that given the amount of accessible information on the Internet today, criminals are easily able to exploit vulnerable individuals like foreign students studying overseas.
Police in Toronto say they've located the second of three students who "went into hiding" after falling victim to an alleged scam targeting their families back in China. The other two students were located over the weekend.
These people then contact the students' families in China, telling them their child has been kidnapped and demand a large ransom. "They don't have a lot of friends or family here in Canada".
