KOLKATA, India, April 1 (Reuters) - Police on Friday opened a case of culpable homicide against the company building a flyover that collapsed in Kolkata, killing at least 23 people and injuring dozens more.
Rescuers worked all night with cranes and jackhammers to clear concrete slabs and steel girders from the 100-metre (110-yard) length of the flyover that broke off suddenly and crashed down on pedestrians and vehicles on the road below.
Ninety were rescued, many with serious trauma injuries, but chances of finding survivors in the wreckage had dwindled nearly a full day after Thursday's disaster in a teeming commercial district near the city's Girish Park.

"It is being ensured that there are no more dead bodies under the debris," S.S. Guleria, a deputy inspector general of the National Disaster Response Force, told Reuters Television.

OVERNIGHT EFFORT
Rescue operations were slow initially, with local residents forming crowds several deep as they tried to help trapped people.
But three cranes working overnight managed to clear some of the wreckage and free access to vehicles with people believed to be still trapped inside.
Harrowing news images showed the leg and arm of one dead man protruding from under a massive steel girder. The broken leg of an unconscious man flapped uselessly as rescuers gripped his other three limbs to carry him away.
Getting survivors to hospital was complicated by a lack of access for ambulances to the flyover, hemmed in by buildings on either side. Safety standards were lax, witnesses said.
"Every night, hundreds of labourers would build the flyover and they would cook and sleep near the site by day," said Ravindra Kumar Gupta, a grocer who pulled out six bodies, together with his friends.
"The government wanted to complete the flyover before the elections and the labourers were working on a tight deadline. Maybe the hasty construction led to the collapse."
