Eight teams of the railway police had been searching for clues to the alleged killer of the woman whose body was found in a local train at Churchgate station on April 25.
First, the railway police found a tag on the murdered woman’s clothes, Paridhan, NK Road, a readymade garment shop. A team was sent there, but found that the shop had been closed down three years ago.
The railways then concentrated its investigation between Vasai and Virar as the fisherwomen who had boarded the train at Vasai had found the luggage kept under the seat. However, they had not seen or heard anything suspicious.
Most of the teams were then asked to find out if anybody had seen anything on the day of the incident between Vasai and Virar. The crucial evidence that the police found after verifying the CCTV footage of the stations on the western line was of a person boarding the same compartment with luggage from Nalasopara on the day the body was found. Following this most of the police teams were diverted to the area and the railway police started roaming around Nalasopara with copies of the hazy images captured by the CCTV camera.
The railway police asked people near stations between Vasai and Virar if they could identify the man to get leads in the case.
