New Delhi - Baby Falak's five-year-old brother has been found in Uttam Nagar here, police claimed Wednesday, while the two-year-old battered girl continued to be critical.
Police found the boy after a tip-off but are still to conduct a DNA test to match it with Falak's mother Munni, an official said.
"We have not yet conducted the DNA test on Munni, Falak's mother. It is likely to be done by this week," the police official said.
The child has been handed over to a child welfare committee, he added.
The boy had been missing for months and a search was launched in Delhi and Bihar after 21-year-old Munni's story came to light.
Falak, meanwhile, continues to be in the same condition, with doctors saying she was stable but critical.
"The baby is still on ventilator and remains critical and stable," AIIMS neurosurgeon Deepak Agrawal told IANS.
"The good news is that the chest and blood infections have resolved. But the brain infection is still a cause for concern," he added.
Another minor surgery was performed on her to drain out the brain fluid. "A tube has been inserted inside the brain to drain the extra brain fluid but this is a temporary solution," the doctor said.
"After the infection in the brain subsides we will do a surgery called shunt surgery, in which we will insert a plastic tube from the brain to the stomach, where the brain fluid will be drained," he added.
Earlier, in a major breakthrough in the case, the Delhi Police Friday arrested the key accused Rajkumar.
Falak was admitted to the All India Institute of Medical Sciences (AIIMS) Jan 18 by a 14-year-old girl who claimed to be her mother. The baby was in a critical condition as her head was fractured and she had human bite marks all over her tiny frame.
Investigations in the case have pointed to a likely human trafficking and prostitution racket, police said.
