The two-year-old boy continues to remain trapped and efforts are on to rescue him.

More than 36 hours have passed since the rescue operation began to find the toddler who fell into an drain in Mumbai on Wednesday night, but with little success so far.

The two-year-old boy continues to remain trapped even as the city's fire brigade, police, ambulance and ward staff have been pressed into operation to rescue him. Angry residents gathered at the site and threatened to block roads if the boy was not found soon.

Here's the video of the rescue operation:

The toddler slipped into the drain at 10:24 p.m. on Wednesday night on busy road in Goregaon. The CCTV footage shows him walking alone on the side of a busy road. Unaware of the open drain, he slips into it.

The boy's father Sandeep Singh said there is no lid on the drain for many years. The residents try to cover it but that's of no use as rain washes it away.

"If this would have happened outside the Oberoi hotel, the lid on the gutter would have been fixed very early but no one gives attention to the slums," he was quoted as saying by news agency ANI.

The Nationalist Congress Party (NCP) and the Congress are demanding action against civic officials whose negligence led to this mishap.

Mumbai Mayor Vishwanath Mahadeshwar has said the person who is responsible for this will be punished.
