A medicine bottle left behind by the woman suspected of kidnapping and then leaving seven-month-old Venkatesh Kale with a man outside a mosque at Marine Lines, may help the police track her down.
In addition to this, the police said the taxi in which reached the mosque may also help the police trace her whereabouts. The police are also scanning through the CCTV footage outside Bombay Hospital, which is near the spot where Venkatesh was left by the woman.
An officer from Azad Maidan police, requesting anonymity because he is not authorised to speak to the media said that every bottle of medicine has a batch number.
"We will contact the manufacturer and ask them for the chemist shop where the consignment carrying the particular bottle was sent.
"If the shop has CCTV cameras installed, it will make our job easier. However, the owner or the person who attended to the woman should be able to give us vital inputs," added the officer.
The police have also roped in taxi unions to help them in their investigation.
The officer added that taxi drivers, especially those plying in south Mumbai, will be questioned. "Once the driver is tracked down, he will tell us where the woman got in and where she was dropped," added the officer.
The Azad Maidan police, are however, relieved that the child is reunited with his mother. "Ever since the child went missing, his mother's health had been failing. Now that they are united, there is a sense of relief," added Anil Surve, assistant inspector, Azad Maidan police.
