About 20,000 bicycles are stolen in London every year. And if your bike is one of those, there's little chance of you either getting it back - or of the thief being caught.

When his was taken, Alasdair Bayman from east London thought he would be another of the unfortunate victims to never see their bike again.

But then he found it listed on an online marketplace.

He cooked up a plan that would not only lead to the recovery of his bike within 48 hours - but also to the arrest and criminal charge of the man thought to have stolen it.

He's been telling his story to 大象传媒 Radio London's Riz Lateef.
