Attracted by the video posted on YouTube, more than 100 uninvited teenagers descended on the family house of Engineer David Worthy, in Chippenham, Wiltshire. They stole whisky and champagne, smashed windows and started fighting. David 53, was punched in the face when he tried to stop a group of youths, while his son Stephen, 18, was badly beaten.
The party for their son Christopher's birthday was supposed to be a small event with about 30 invited guests. However, details were posted on the Internet, that attracted dozens more teenagers.
Wiltshire Police arrested six teenagers aged between 15 and 18. Four were held on suspicion of causing grievous bodily harm, while two others were detained for public order offences. Later, they were all bailed. Link
