New Delhi: Delhi Police Thursday appealed to witnesses to come forward and identify the man who shot dead 20-year-old Delhi University student Radhika Tanwar near her college in south Delhi Tuesday morning.
"We have found certain vital clues and have narrowed down our investigation and we have definite lines on which we are working," Deputy Commissioner of Police HGS Dhaliwal said.
After the sketch of the victim`s alleged stalker was released Wednesday, two people had given the police some information which helped significantly, Dhaliwal said, "but still no witness has come forward despite our requests."
"We would request anyone who was present there at the time of the crime to come forward and talk to us, maybe discretely. Otherwise, the investigations would be long drawn," added Dhaliwal.
The police also said that Radhika and her family knew that someone was stalking her for the past three years, but did not lodge a complaint.
"We respect the family decision as many people try to solve these problems personally," he said.
Dhaliwal said preliminary investigations show that Radhika`s stalker was staying near her house in Naraina village area.
Village locals had earlier beaten up some youths for harassing women of the area.
"We are looking into all these. These are three different cases," Daliwal said.
He said police will verify each of the around 3,000 people who had stayed in Naraina village in the past three years. The area houses many migrant workers, mostly from Uttar Pradesh and Bihar.
"We will be verifying everyone," he said.
Radhika, a resident of Naraina area in west Delhi, was a student of Ram Lal Anand College, located in Shantiniketan, south Delhi.
According to police, she was crossing a foot over bridge near Dhaula Kuan when suddenly a man shot her from behind at around 10 a.m. and disappeared into the crowd of students and office-goers.
