The suspects were reportedly affiliated through the 'Bhagat Singh Fan Club' on Facebook, with suspicions of external direction. A Special Cell team is set to question a person in West Bengal associated with the case.

"We have bolstered our presence at key locations and are maintaining constant vigilance to prevent any untoward incidents," said a senior police official. 

According to the officials, the case pertains to a passenger who caused disruption on the flight and directed offensive language at the female cabin crew.

The deceased has been identified as Anil Sisodia, a resident of Jangpura, who was posted at Southwest district police headquarters. 

A Delhi court on Wednesday also remanded to seven days of police custody.

The police have also arrested Shahnawaz's two associates and recovered incriminating materials from their possession, including those suspected to be used in IED fabrication.

“Delhi Police personnel, along with paramilitary forces, have been stationed outside the High Commission of Canada in Chanakyapuri as a precautionary measure,” the officer said.
