Three top officials of a Hyderbad-based construction company, which was building the city flyover that collapsed, were on Saturday remanded to police custody for nine days by a Kolkata court.

They were arrested on Saturday night and the police have slapped murder charges on them.

The three officials of IVRCL were remanded to police custody by the city civil court a day after their arrest by Kolkata Police.

The three are Assistant General Manager Mallikaarjun, Assistant Manager Debjyoti Manjumdar and Structure Manager Pradip Kumar Saha. They were arrested under IPC sections 302 (murder), 307 (attempt to murder) and 120B (criminal conspiracy) and others.

Police had registered a case against the construction firm under sections 304 (culpable homicide not amounting to murder), 308 (attempt to commit culpable homicide) and 407 (criminal breach of trust) of IPC and sealed its local office after the under-construction flyover collapsed in the city on March 31 leaving at least 26 dead.

Earlier, the police had detained 10 officials of the Kolkata office of IVRCL for questioning, a senior Kolkata Police officer said.
