Justice S S Sateeshchandran made the observation while dismissing the bail applications filed by accused civil police officers Ajeeb and Savad.
The probe should also look into the alleged involvement of senior officials of immigration and police, the court held.
Ajeeb while working at the airport from 2007-2011 had helped various travel agents in sending people abroad without proper documents. The Crime branch suspects that over 150 people had travelled to other countries with assistance of Ajeeb and his gang.
