And Phil Hoyle, of the APFU, says the curious lack of blood or footprints at the scene - despite the surgical removal of large amounts of tissue - means extraterrestrials can't be ruled out as the cause of the attacks.
These marauders, or pirates, came from Scandinavia--what is now Denmark, Norway, and Sweden. The people who lived there were Norsemen, or Northmen. Those Norsemen who took part in these swift, cruel raids along the coast were called Vikings. The Vikings came to be the most feared raiders of their time and were the only Norsemen with whom most Europeans came in contact. Their name was given to the era that dated from about AD 740 to about 1050--the Viking Age.
The Vikings (Danes or Norsemen) began their invasions as early as 787 but the main attacks on the south and centre of the country started in the reign of Egbert (802-339). Egbert, the King of Wessex led the defence of the country and in 837 inflicted an important defeat at Hingston Down in Cornwall.
