What began as a honeymoon trip to Bangkok Saturday morning ended in a daylong nightmare for actor and Jessica Lall murder witness Shayan Munshi after he was arrested at the airport here and then kept in a court lock up for hours before he got bail in the night.

After daylong confusion and confinement in the Barrackpore court lock up here, Munshi was produced before sub-divisional judicial magistrate Gopal Karmakar around 6 p.m. who granted him bail on a personal bond of Rs.5,000.

He was, however, asked to deposit his passport with the airport police here and appear before Mehrauli police in New Delhi where a case was registered against him recently.

Munshi, against whom the Delhi Police issued a look out notice in the Jessica Lall case, was detained at the Netaji Subhas Chandra Bose International Airport by the immigration officials while trying to board an Indian Airlines plane.

"Shayan Munshi was detained by immigration officials while trying to go to Bangkok. He was later handed over to the police," a commandant of the Central Industrial Security Force (CISF) told.

It was not just the honeymoon that went awry for Munshi as he was kept in the Barrackpore court lock up till Saturday evening without being produced. There was confusion about the exact cause of his arrest with West Bengal police avoiding communication with media persons and his family alike.

"We were asked to sit aside at the airport. It happened because of a miscommunication between the economic offences wing, Delhi and Kolkata police and immigration department," Munshi's actor wife Peeya Rai Chaudhary had said earlier.

"We have been busy since our marriage in December. Today we were leaving for honeymoon in Bangkok," said Peeya who played Aishwarya Rai's sister in "Bride and Prejudice".

Munshi, who hails from Kolkata, was shooting for Anjan Dutta's film "The Bong Connection" here. Wife Peeya also acted in the film shot in Kolkata and the US.

He is one of the key witnesses in the murder of Jessica, who was working then as bartender at New Delhi's Tamarind Court restaurant in Mehrauli area.

Munshi was one of those who turned hostile as the case progressed, leading to the acquittal of the key accused Manu Sharma and others.

Sharma, the son of Haryana politician Venod Sharma, is accused of shooting Jessica after she refused to serve him a drink at Tamarind Court where Munshi was also a bartender.

On Feb 21, a court acquitted all nine accused in the case, including Sharma, for lack of evidence, police inefficiency and backtracking of witnesses.

The ruling caused outrage, and the case was reopened for trial. Jessica's sister Sabrina is spearheading the campaign for justice in the case.
