Siri tells boy aged 12 to Shut the f*** up in Tesco

A 12-year-old boy was told to "Shut the f*** up, you ugly t***"  while he tested out the iphone 4S on demo in a Tesco supermarket in Coventry.

The boy had been using the phone's Siri system – which answers spoken questions – and had asked it: "How many people are there in the world?"

His mother said "The phone was a demo version and was low enough on the shelf for Charlie to have a go with. He asked it a simple question and we couldn't believe the filth it came out with.

"I thought I must be hearing things. So we asked again and the same four-letter stuff blared out.

"I asked for the manager and after staff heard it they agreed to unplug it. I couldn't see the funny side."

Tesco said: "We have launched an investigation. The handset will be going back to Apple for diagnostic tests."
