The Chennai police released on Thursday a photograph of the main suspect in the murder of Infosys employee Swathi Santhanagopalakrishnan, who was hacked to death at a railway station on way to work last week.
Though officials have rounded up 20 people, they have yet to make a breakthrough despite releasing CCTV images of the suspect earlier. The Madras high court has warned the state government against slow probe.
A police spokesperson said the suspect -- the new photo showed a man wearing a checkered shirt carrying a backpack -- did not speak to the 24-year-old Swathi before attacking her at Nungambakkam railway station.
“The fact that he did not speak to her does not rule out that he was known to her,” an official said, adding the murder weapon --- a sickle --- was sent for forensic tests.
Officials said the image too was sent to a lab in Hyderabad for enhancement. Police said the photo was ‘developed’ by them.
An eyewitness told a Tamil news channel that Swathi did not make a sound when the man attacked her.
Swathi was employed with Infosys’ branch at Mahindra World City at Singaperumalkoil, around 60km from Chennai. Her murder has triggered outrage in the civil society and among political parties.
After the high court’s intervention, the state government transferred the investigation from the Government Railway Police to the city police on Monday.
Her father has said the people at the crowded station remained mute spectators even as Swathi was attacked.
