Feeling blue: drug dealer’s ‘love of stilton’ leads to his arrest

From the article:

> A drug dealer’s “love of stilton” has been credited for his downfall after police were able to identify him from a photo of his hands holding a block of cheese.

> Carl Stewart, 39, was identified after he shared the photo on the encrypted messaging service EncroChat, from which police were able to analyse his fingerprints.

Did it really, or is that the "parallel construction" cover story?
