Bernie Ecclestone's Daughters Bodyguarded In Bev Hills After Mother-In-Law Abducted

Bernie Ecclestone's family isn't taking any chances after the Formula One boss' mother-in-law was abducted in Brazil -- his daughters are now rollin' with a full security detail, TMZ Sports has learned.

Tamara and Petra Ecclestone took their kids out for a stroll in Beverly Hills Tuesday -- flanked by a team of at least 4 huge plain-clothed bodyguards (you can even see the earpieces).

The daughters were mum about the active ransom situation involving Aparecida Schunk -- the mother of Bernie's wife, Fabiana Flosi -- who was taken Friday night in Sao Paulo.
