A 40-year-old magician who went missing after being lowered into a river while tied up with chains and ropes in a Harry Houdini-inspired stunt is feared drowned, police said Monday.

Eyewitnesses said Chanchal Lahiri, who was lowered into the river standing in a six-foot-tall cage having six locks, from Millenium Park for the underwater escape act, disappeared near pillar number 28 of the Howrah Bridge.

Lahiri, a resident of southern suburbs of Kolkata, had done the same trick in 2013 in same Hoogly river, but this time he ran out of luck and drowned.

Six years ago, people watching his stunt show had reportedly assaulted him after seeing through his trick. The magician was trying to do escape act popularised by American stunt performer Harry Houdini nearly a century ago.

The police along with Disaster Management Group began a search for him on Sunday after receiving information that he did not emerge from the river.

“We tried to spot him. But it seems the stream has swept him away. Our divers dived deep, but could not locate him.”

“Because of darkness, we had to temporarily stop our search operation on Sunday evening,” a senior police officer said.

Lahiri had taken permission from both Kolkata Police and the Kolkata Port Trust, police said.

“He had mentioned the act was to happen in a boat or vessel and there was no connection with water. Hence we allowed him permission.

“However, he vaguely mentioned an ”extra act” which he did not clarify. We are investigating,” a senior police officer said.

Lahiri took a ferry from Fairly Place Ghat at around noon to perform the magic, an onlooker said. “The magic that Lahiri was to perform was very risky and complicated,” he said.

He was not only to be blindfolded, but his hands and legs were also to be tied up. He was to be picked up in that position from the boat by a crane, stationed on the Howrah Bridge, that would, in turn, lower him into the river. The magic was that he would come up from the water, by untying himself on his own.

Accordingly, he went to the middle of the river just underneath the bridge from where he was picked up by the crane and thrown into the river near pillar number 28 of the bridge.

The spectators who had gathered to cheer him started to panic as it was more than ten minutes and Lahiri was not coming out of water.

Some of the spectators called up the local North Port police station for help. Policemen rushed to the spot along with Disaster Management Group and started a search for Lahiri.

Four divers were looking for his body, though it could not be fished out till late evening. “We have started an investigation into the matter and as to how a crane reached the Howrah Bridge,” the police officer said.

This was not Lahiri’s first misadventure. He had declared a decade ago that he would walk on the river but had to beat a hasty retreat when the act went wrong.
