The Delhi Police has issued a lookout notice against three pilots and a flying instructor to ensure they did not flee the country in the fake pilots scam. The look out notices were issued by the Delhi Police's crime branch against pilots Swaran Singh Talwar of MDLR, Syed Habib Ali and Bhupinder Singh for allegedly being involved in forging marksheets to procure flying licences. A senior police official said that the three persons possess licences but have not joined any airline. Similar notice has also been issued against a flying instructor D Asatkar. A senior official of airline regulator DGCA and three others, including a pilot, were arrested on Saturday with Delhi Police claiming that it has smashed a racket involved in forging marksheets to help pilots procure licences.
