LONDON, England -- Worried UK parents are asking to have tracking microchips implanted into their children following the murders of two 10-year-old girls, a cybernetics expert says.

Scientist Kevin Warwick from Reading University, west of London, says parents can keep track of their children with a tiny microchip implant in the arm or stomach.

Such a chip could prevent an abduction from becoming a murder, he says.

"A number of families have contacted me after the murders of Holly Wells and Jessica Chapman with the possibility of using an implant for their own daughter," Warwick told Reuters.
