British online retailer Play. com leaked the personal details of numerous customers by sending emails containing personal information to the wrong customers.
Many customers received emails reporting the dispatch of orders they did not place, and when the emails were opened they revealed the names and addresses of other customers of the online retailer.
A Play. com customer told BBC that he received more than 80 emails and each email revealed other customers' names as well as orders placed by them.
But, the emails did not contain any financial details of the customers.
When contacted, Play. com said, "We take these matters very seriously and are now investigating how this incident occurred in the first place, so that we can prevent it happening in the future."
