Chennai, Jun 30 (PTI): A photo of the suspect in the murder of a 24-year-old woman IT professional was today released by the city police, four days after they made public CCTV images of the incident at a railway station here.

Police released a 'file photo' of the man, saying it had been 'developed' by them. The photo shows a man wearing blue shirt and black pants, similar to what was seen in the CCTV footage released by the police on Sunday.

No further details were made available.
Police are yet to crack the murder of S Swathi, who was hacked to death on Friday at the busy Nungambakkam railway station, prompting a furore by the civil society and political parties.

The woman, employed with IT major Infosys, was allegedly killed by an unidentified man on a platform while she was waiting to board a train on her way to office around 6:30 AM.

The Madras High Court had also come down on the state government, warning it of suo motu intervention if there was any slackness in the probe.

The probe, originally done by the Government Railway Police, was later shifted to the city police who have now formed eight special teams to crack the murder. 

The weapon believed to have been used in the murder, a sickle, had been recovered last week from the railway track near the station premises, police added.
