A 45-year-old sheep farmer, Nigel Wright, was found guilty of contaminating baby food with shards of metal and blackmailing supermarket staff about their whereabouts.

Hertfordshire police footage showed Wright placing tamperedjars on a supermarket shelf before he left with flowers for his primary school teacher¢¥s wife and a bottle of wine. Wright blackmailed three major food companies, including a demand of 1.5 million pounds in bitcoin from the company Tesco, in exchange for revealing where the contaminated food had been placed.

Tesco was forced to issue a product recall when two mothers discovered pieces of metal in jars of baby food. The man is due to be sentenced at the end of September, and he is facing up to 17 years in prison.

Difficult words: shard (a small sharp piece of broken metal, glass or rock), whereabouts (the place where someone or something is), tampered (changed in order to cause damage), issue (to put out formally).
