I think it is important that mums are always alert with their kids and strangers - however I also heard this story from a friend. I googled it and came up with this blogg which suggests its actually just an urban legend. I dont know if it is or not, and it doesnt mean mums should relax about the safety of their kids.

I've copied part of it below:
Is Hong Kong really that safe?
Update - looks like the Ikea story is an urban legend after all. After talking to a few people who insisted the story sounded fishy and Gweipo's comment below that she had heard this story before, I did a little more digging around and found the same story written about an attempted kidnap in large supermarket chain Tesco, in Bangor,UK where a little girl was found in the washrooms with her head shaved. Apparently this urban myth was so widespread the company had to issue a statement to the press in an article titled 'Supermarket chain quashes Bangor child abduction rumour'. Sorry, didn't mean to scare you parents!! Like Irene said, Hong Kong maybe one of the safest cities in the world after all.
I received the following email today (thanks Carla),
Ikea - Attempted Kidnapping
Just wanted to let you know that a friend of one of Nathan's* playgroup friends was involved in an attempted kidnapping at IKEA Causeway Bay a few weeks ago. Apparently, the boy was 3yrs old and ran ahead of his mother in IKEA. When she couldn't find him, she alerted security who then shut all the exits. They eventually found the boy in the IKEA bathrooms with his head shaved and clothes changed! They didn't find the people who did this to him. Scary times.
*boy's name changed for privacy
