Chennai: A 24-year-old woman software engineer, working with Infosys, was hacked to death by an unidentified man at Nungambakkam Railway Station on Friday morning even as aghast commuters looked on.
The police on Friday night released the footage of the killer. Video footage that investigators picked up from a house outside the railway station showed a man crossing Sowrashtra Nagar Road in a hurry at 6.43 am.
A shopkeeper on the platform told the police that he saw a man in his 30s arguing with Swathi and then attacking her with a knife.
He informed the railway staff who alerted police. Investigators said Swathi's cell phone was missing and that the killer may have taken it to destroy evidence. The GRP have registered a murder case and are investigating.
