The grandfather of the alleged victim said the unidentified 10-year-old of Asian descent might have been influenced by recent gruesome scenes from Iraq on television, the Mirror reported Monday.
"What the boy did must be connected to what's happening in the news with terrorists beheading people," said the victim's grandfather, Paul Williams. "He must be copying what he's seen."
Police allege the boy boasted to friends he was "a trainee Iraqi assassin" and a few days later he waved a Stanley knife under Williams' chin, saying, "I'm going to cut your head off."
The incident occurred three days after the beheading of U.S. hostage Jack Hensley in Iraq last month; however it only came to light after British hostage Ken Bigley had been executed by his captors.
