Customer finds a human bone tucked inside a newly-purchased pair of socks

Whether legit or not, plenty of people have reported finding at least a piece of a human finger in their food (from thumb skin in an Arby's sandwich to a finger in Kohl's Frozen Custard, according to NPR). But I don't recall a human body part ever found in newly purchased clothes, until now.
Allegedly, someone bought a pair of socks at a Primark store in Colchester, England, and found the added bonus of a human bone tucked inside one of them.
From The Guardian:

“Detectives are continuing to investigate following the discovery of what is believed to be part of a human bone in a pair of Primark socks,” said a police spokesman.
“The bone does not appear to be a result of recent trauma and had no skin or other particles surrounding it. We are liaising with the store who, in turn, are speaking to their suppliers for more information on this incident. Inquiries are ongoing.”

In the cases of food, it's usually part of a severed finger after an unfortunate accident in the kitchen. In this case, however, although the bone is real, police suspect it is was placed in the sock as a hoax.
“No evidence of any kind exists to suggest that any incident has occurred in the factory, so it is highly probable that this object was placed in the socks by an individual for unknown reasons...Primark sincerely apologises to the customer who found the item for any distress caused,' says a Primark spokesperson.
