Police on Tuesday filed chargesheet before a city court indicting 10 people for culpable homicide among other offences, in the flyover collapse case that claimed 26 lives.
The move came on a day when police arrested two engineers of the Kolkata Metropolitan Development Authority.
A portion of the under construction Vivekananda Road flyover in the city's Posta area had collapsed March 31 killing 26 people besides injuring over 100.
While the 10 accused arrested in the case were initially booked for murder among other offences, the police in the chargesheet have not included the charge.
Joint Commissioner of Police Vishal Garg refused to comment on the withdrawal of murder charges citing the matter to be "sub judice."
All the 10 accused currently in judicial custody are employees of the Hyderabad-based IVRCL, the company executing the project.
The two officials arrested on the day - Priyatosh Bhattacharya and Santanu Mandal - will be produced in a court on Wednesday.
