Even as five persons were booked and a senior engineer arrested for the collapse of an under-construction flyover, uproarious scenes were witnessed in the Odisha assembly on Monday as the opposition demanded Chief Minister Naveen Patnaik’s resignation.

The Speaker adjourned the house for one hour and then again till 3 p.m. as pandemonium prevailed over the issue.

The incomplete flyover collapsed in the Bomikhal area in Bhubaneswar on Sunday, killing one person and injuring 11 others.

As soon as the house assembled for the day, several Congress and Bharatiya Janata Party members rushed to the well of the house and shouted slogans demanding Patnaik’s resignation while he was making a statement on the incident.

“One precious human life was lost and 11 persons were injured. The injured were immediately rushed to the Capital Hospital and All India Institute of Medical Sciences, Bhubaneswar. Special arrangements were made for their treatment,” Patnaik said.

He said Rs 5 lakh had been sanctioned for the family of Satyabrata Patnaik who lost his life.

“The Deputy Executive Engineer and Assistant Engineer concerned have been placed under suspension. A high-level inquiry has been ordered. My government will ensure that stringent and exemplary action is taken against those responsible,” he added.

Police Commissioner Y.B. Khurania said on Monday that Deputy Executive Engineer Bansidhar Praharaj was arrested after a case was registered against him and four others, including three top officials of construction company Panda Infra handling the project.

He said a case was registered against Praharaj and Assistant Engineer Kishore Rout, besides the company’s Board of Directors members Sujata Panda, Pratap Panda and Santosh Panda under Sections 304, 337, 338 and 34 of the Indian Penal Code at Laxmi Sagar police station.
