Brad Pitt took a swipe at his ex wife Angelina Jolie for letting him ride a bike, instead in a car.
A source told DailyMail.com, 'Brad is distraught and worried over Pax's accident, but he is unable to reach him'.
'It is very upsetting to Brad whenever he hears of one of the kids being hurt and he feels completely powerless because there is nothing that he can do at all.'
'A father's inclination would be to go to the hospital, or to call him. He's tried so many times but the kids won't take his calls. His hands are tied.'
'Brad doesn't think that Pax should be driving a scooter without a helmet to begin with - he should have been in a car'.
