Delhi Police have issued a lookout notice against three pilots and a flying instructor for allegedly forging marksheets to procure pilot licences.
The pilots Swaran Singh Talwar of MDLR, and Syed Habib Ali and Bhupinder Singh, had allegedly procured Airlines Transport Pilot Licence (ATPL) using fake documents.
"The lookout notices are issued to prevent them from fleeing the country. All airports and ports have also been put on high alert," said the police.
Delhi Police have so far arrested six people, including Pradeep Kumar, an assistant director with airline regulator Directorate General of Civil Aviation (DGCA), for their involvement in the scam.
During interrogation, Kumar told police that he had processed files for around 60 licences in the past couple of years.
