Rajya Sabha MP Kapil Sibal on Monday raised a series of questions over the killing of Atiq Ahmad and his brother, asking why they were being taken for a medical checkup by police at 10 pm when there was no emergency and why it was "open to the media".

Gangster-turned-politician Ahmad and his brother Ashraf, both in handcuffs, were shot dead by three men posing as journalists on Saturday night when they were answering reporters' queries while being escorted by police personnel to a medical college in Prayagraj for a checkup.
