Firefighters in London are being called out nearly every hour to rescue people who have locked themselves in or out of a building or vehicle.
London Fire Brigade (LFB) said in the last three years it had been called out to nearly 22,000 incidents of this type - 20 each day.
The brigade said it has been called out to people trapped in cemeteries, toilets and cupboards.
It estimated this costs taxpayers more than £5m.
