A Bangladeshi worker has been crushed to death while working in the tunnel portion of the Klang Valley MRT - the first underground fatality since the project started in 2012, reports the Star.

Saifikul, 28, who worked for SP Mega Sdn Bhd, the subcontractor engaged by the main contractor MMC Gamuda KVMRT (T) Sdn Bhd for reinforced concrete, was dismantling temporary structures at the Tun Razak Exchange station.

Slabs of concrete fell on him at 1.15am Sunday. His fellow workers escaped unhurt.

He was rushed to Hospital Kuala Lumpur and died of his injuries.

SP Mega is making arrangements to inform the Bangladesh High Commission.

The accident site has been sealed for investigation by the Occupational Health and Safety Department and other agencies.
