Who is helping Maulana Saad escape police's clutches?

The Crime Branch of Delhi questioned one of the sons of Maulana Saad of Nizamuddin Markaz on Monday. And now it is suspected that the Maulana will be arrested soon. 
His second son revealed details about the regular attendees of Tablighi Jamaat events that used to take place at the markaz in Delhi. Few of them used to arrive via chartered planes too

Four notices were sent to Maulana Saad too but he never replied. Now, his lawyer claims that the authorities know where Saad is. So is there someone helping Saad?
