Dr Naveen Khichi, owner of New Born Baby Care Hospital in New Delhi's Vivek Vihar, where a blaze led to the deaths of seven newborn babies on Saturday, has been arrested, news agencies report.
Television channels reported that he was arrested in Delhi, though it was being speculated that he had fled to Jaipur after the fire broke out.
It's believed Khichi owns several childcare hospitals.
New Born Baby Care Hospital did not have fire safety no-objection-certificates and had oxygen tanks in the building which exploded as the fire spread.
Of the 12 newborns who had been rescued, seven have died.
Cases under multiple sections of the Indian Penal Code (IPC) were registered against Khichi, with charges under Section 304 (related to culpable homicide) of the IPC also likely to be slapped on him
It has also emerged that the hospital was linked with incidents of criminal negligence in the past, according to India Today.
Khichi was booked for alleged mistreatment of a newborn at the hospital, India Today reported.
An FIR had also been lodged against him by a couple from Hathras in Uttar Pradesh after they acquired CCTV footage from the hospital to find out how their baby's hand had been fractured and saw a nurse physically assault the newborn.
The fire broke out late at night. Delhi Fire Services (DFS) received a distress call at 11:32 p.m. regarding a blaze at a baby care centre.
Twelve newborns were rescued, but tragically, seven succumbed to their injuries while receiving treatment at the hospital. Five other children are currently under medical care.
According to DFS chief Atul Garg the cause of the fire is yet to be ascertained.
The fire could have spread quickly because of the explosion of the numerous oxygen cylinders in the building.
Garg told television channels that a call was initially received at 11.32 pm on Saturday.
Seven fire engines and later 14 were sent to the spot.
"There were 4-5 explosions that significantly worsened the fire, with oxygen cylinders being hurled as far as 50 meters away," he said.
The unit for the newborn babies was on the first floor of the building.
