NDRF Director General O P Singh told PTI the force's personnel have scoured the entire accident area and there were no more "dead or live victims". However, there is a possibility of one body still being trapped.
"We have thoroughly examined the area and there is no evidence of any dead or live victim. But, despite this, all the 10 teams sent for the task will be on standby till the West Bengal government asks them to retreat," he said.
Twenty four people were killed and around 90 injured after a 60 metre-long stretch of the 2.2 km under-construction flyover had crashed down yesterday afternoon on a congested road intersection in Kolkata. The condition of seven persons hospitalised is stated to be "very critical".
Responding to the emergency, NDRF had sent teams from various locations to the accident site for rendering rescue tasks.
