As far as the news story goes, it was in most of the Chinese language media last week. And mothers are going crazy about it!
The specific incident that kicked it off happened in Harbour City near all the children's shops. Two young guys, early to mid-twenties, tried to pick the little kid up and walk off with her. When the mother confronted them they left the kid and pretty much ran off and wouldn't speak to her. The mother was quick enough to get a very good face picture of the two guys and alerted the security (who predictably screwed up and didn't even make it to the guys to confront them).
May be nothing...but didn't sound like nothing.
