Police suspect that on Friday, the stalker followed her and pounced on her soon after Gopalakrishnan left.
“We have collected more CCTV footage from houses and shops outside the railway station. We are studying whether he made a recce before the attack,” a police officer told TOI.
On Monday, the city police took the case diary and evidence from the government railway police. An officer said that it is like starting a case from scratch and they need to study all the evidences and also look for new things, according to TOI.
Police claim that he walked on the tracks from Nungambakkam railway station to Kodambakkam station and went out through an opening on the Choolaimedu High Road.
