'My son would speak about Headley only if authorities allow him'

Filmmaker and social activist Mahesh Bhatt said his son would divulge any relationship with US terror suspect David Coleman Headley only if the authorities give him the green signal. Media reports say the mysterious name, Rahul, mentioned extensively in Lashkar-e-Toiba (LeT) operative Headley's e-mails to handlers in Pakistan, refers to son of Mahesh Bhatt.
