Even after questioning over 30 people, the police are yet to find a lead in the murder of a 59-year-old woman in east Delhi’s Madhu Vihar, the police said on Sunday. She was shot dead by bike-borne assailants on Saturday.

An officer said they have obtained 20 CCTVs from the possible escape routes taken by the two assailants after the murder.

“We have questioned the people who hold criminal records to get a clue in the case. CCTVs are being scanned,” the officer added.

The incident took place when the woman was driving her husband to Max Hospital in Vaishali for his dialysis. “In a CCTV footage near the crime spot, two men on a black bike can be seen opening fire at the woman. We are tracing the motorbike. It could be the robbers, who live in Ghaziabad and operate in Delhi,” added the officer.

‘Act of desperation’

The motive of murder will be clear only after the accused are nabbed, the police said, adding it could be an act of desperation after a failed robbery attempt.

The victim, Usha Gupta from Radhey Shyam Park Extension, worked as assistant manager at New India Insurance company.

A murder case has been registered and teams are probing all angles, including personal enmity, the police added.
