Ajanta Manufacturing Limited (Oreva Group) was responsible for the operation and maintenance of the British-era suspension bridge on the Machchu river that collapsed, with a special investigation team formed by the state government citing several lapses on the part of the firm.
The police had on Monday booked nine persons under Indian Penal Code section 304 (culpable homicide not amounting to murder).
Patel, whose company was responsible for the operation and maintenance of the bridge, surrendered before the court on January 31 after it issued an arrest warrant against him. He was later arrested by the police.
While the flooring of the bridge was replaced, its cable was not replaced and it could not take the weight of the changed flooring, said the prosecution, citing a forensic report.
