The district administration was not informed by the organisers that the inaugural ceremony of the Great Adventure Mall would also feature adventure sports.
Departments such as sports, police and entertainment tax were kept in dark.
"We were only aware that Union tourism minister Subodh Kant Sahai would inaugurate the ceremony," said Pawan Kumar, chief development officer of Gautam Budh Nagar district.
A 26-year-old bungee-jumping trainer, Shailendra Kumar Bisht, lost his life, while actress Sayali Bhagat was injured while performing stunts at the mall.
The administration is conducting a probe to find out the reason behind the accidents and fix responsibility.
"We have registered an FIR against the organisers. We had no information about any adventure sports taking place," said senior superintendent of police (SSP) Praveen Kumar.
Bisht was rushed to Kailash Hospital where he was declared brought dead.
"That the trainer had to be taken to Kailash Hospital, which is 15 km from the accident site, speaks volumes of the preparedness," said an official. He said there were no security measures in place to avert any untoward incident. There were no ambulances, safety net for the stuntmen, first aid or paramedics at the mall, he said.
"He had lost the battle by the time he was brought to the hospital. We have sent the body for post-mortem. Actress Sayali Bhagat has had her right hand fractured," said a doctor at Kailash Hospital.
"Even after the two accidents, the mall management did not stop inaugural activities. We had to go there and shut everything," said a senior police official.
The mall did not even deposit entertainment tax. "No tax has been deposited. We're looking into the details," said an official. No representative of the mall could be contacted for comments.
District sports officer Prem Kumar said, "The organisers did not take any permission. No tax was deposited."
The mall had lined up several events such as helicopter joyrides, para motor acrobatics, bike stunts, rappelling, rock climbing, all terrain vehicle rides, bungee-jumping and many more.
Bisht was rappelling down the outer glass walls of the mall when his hands slipped from the harness rope near the seventh floor.
