Thiruvananthapuram: A court here on Tuesday granted conditional bail to Youth Congress vice president and former MLA KS Sabarinadhan in the case over alleged conspiracy behind in-flight protest against Chief Minister Pinarayi Vijayan. 

He has been asked to furnish a bail bond of Rs 50,000 in the court. While granting bail, the court also asked Sabarinadhan to produce his mobile phone before the court.

The court also directed the Youth Congress leader to appear before the probe team for three-day interrogation in the case.

It was on Tuesday morning, Valiyathura police arrested Sabarinathan accusing him of hatching a conspiracy behind the protest against the CM inside a flight.

The police had on Monday served notice to Sabarinadhan for questioning as part of investigation into the incident of in-flight protest staged by Youth Congress activists against the Chief Minister.

The action comes after a screenshot of a purported chat from a WhatsApp group went viral. In the chat, Sabarinadhan purportedly suggested members of the group to protest onboard the aircraft.
