The Italian doctor at the center of the Lance Armstrong doping scandal could be about to face criminal charges.

In a rare media interview, Padua prosecutor Benedetto Roberti also called for an Interpol-like agency dedicated exclusively to international doping investigations like the one used for Armstrong.

Roberti has been leading a sweeping investigation of Dr. Michele Ferrari for several years, parts of which were used in the U.S. Anti-Doping Agency's 200-page report detailing why it banned Armstrong for life and ordered him to be stripped of all seven of his Tour de France titles.
