What would you do if you were caught stealing a diamond? Drop it? Hide it? Swallow it? That's what this diamond thief did. And when he got caught, the police waited for the diamond to come out, em, naturally. But it wasn't coming out!

The case study says:
The patient underwent a total colonoscopy in the presence of
police officers that easily allowed uncommon stone retrieval using a basket catheter
