Mumbai Chhatrapati Shivaji Maharaj Terminus railway station was put under high alert following a bomb threat. Police and security agencies stepped up security arrangements at the railway station, officials said on Sunday.

“The caller, using the mobile number 9420112655, claimed that a bomb had been planted at the CSMT railway station,” the officials said.

Upon receiving the threat, a dog squad and a bomb detection and disposal squad were immediately dispatched to the railway station. A thorough search operation was subsequently conducted at the entire railway station premises. The search operation was concluded around 9:30 p.m., revealed no suspicious objects or explosive materials.

The railway police later informed that the matter to the main control room and efforts are underway to locate and identify the individual who made the threatening call.

The threat comes as railway stations across India are witnessing a massive crowd as people rush home or are coming back to the city amid the festive season.
