A woman who was wounded in celebratory firing during a New Year's Eve party at former JDU MLA Raju Singh's farm house died even as the legislator and his driver were arrested Thursday, police said.
A hospital source said Archana Gupta died on Thursday.
A pistol and a rifle were seized from the car in which Raju Singh fled from the spot after the incident, Special Commissioner of Police, Law and Order (south), R P Upadhyay said.
"We have arrested Raju Singh and Hari Singh in connection with the incident. They will be produced in a city court later in the day. Police will seek their remand for seven days," he said.
On Wednesday, they were detained in Uttar Pradesh's Gorakhpur city.
Police had earlier seized two rifles and 800 bullets from Raju Singh's farm house in south Delhi's Vasant Kunj area.
In his complaint to police, Archana Gupta's husband had said that they were at the farm house on Monday night to celebrate the New Year along with friends and around midnight, two-three rounds were fired by Raju Singh.
Immediately, he noticed that his wife had fallen down and was bleeding.
The Delhi Police was informed and a medico-legal case was registered, a hospital spokesperson said.
Raju Singh was booked under relevant sections of the Indian Penal Code and the Arms Act, police said, adding that he has five other cases registered against him.
