The daylight robbery caught on a security camera is every parent's worst nightmare. On the tape, Lucy-Leigh Redfern, a 10-year-old from Cleethorpes in the UK, leaves her bike unattended at the entrance to her local convenience store. Moments later a man simply walks up and takes it, leaving Lucy to break into tears when she finds her bike is missing.

It's the kind of story that outrages parents everywhere, except this time most are laughing about it.

That's because Lucy's parents, mom Becca and stepdad Steve, were the ones who pulled off the heist.

The couple revealed that they bought Lucy the bike, which cost around $200. They warned her to lock it up, but often caught her ignoring their advice, so they decided to teach her a lesson.

"I've got a little boy too and I'm always telling the both not to leave their bikes anywhere," Becca says. "She knows better but kids are kids and they take chances."

Lucy was obviously shaken when she found her bike was missing, and cried while she asked people nearby if they had seen who took it. She even asked the convenience store clerk if she could check the security camera footage, leading her parents to reveal the prank to her.

"I was definitely a bit angry," Lucy says, "but it proved a point not to leave my bike outside. I've learned my lesson and I won't do it again."

Other parents have been sharing their reactions to the video online, and Becca was surprised by what they had to say.

Surprisingly, most people think the joke was harmless, and some shared stories about similar pranks pulled by their own parents. As for Lucy, she's promised to be more careful about locking her bike up from now on.

"She's obviously got over the shock now. There's no way she'll do that again," said Becca.

"She was so angry with us at first but my son thought it was hilarious."
