No explanation can be found for the human finger bone that turned up in a pair of socks in Primark’s Colchester branch in January.
Essex Police have been unable to find any information about the grisly find, and have closed their inquiry.
The force said that the mystery has investigated as far as was “reasonably and proportionately possible,” a police spokeswoman said.
She continued: ”At this time it is not linked to a criminal act,” adding ”it is a possibility [the bone] was placed in the sock in its country of origin, but this cannot be confirmed.”
The spokeswoman said that the phalanx – one of 14 that are to be found on every normal human hand – “did not appear to be a result of recent trauma and had no skin or other particles surrounding it.”
She concluded by saying that if any further information came to light, the case would be reviewed.
Primark instigated an investigation of the unexplained finger bone at the time of its discovery but came up empty-handed. They said: “Primark clearly takes this matter very seriously and has already carried out an investigation at our supplier’s factory where the socks were made.
“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 has been the subject of isolated incidents in the past which have subsequently been found to have been hoaxes.
“The factory has been used by other retailers and subject to many audits over many years.
“Primark sincerely apologises to the customer who found the item for any distress caused.”
