The Delhi Police on Wednesday arrested Rohit Shekhar Tiwari's wife Apoorva for her alleged role in his murder, a week after the son of former Uttar Pradesh and Uttarakhand Chief Minister ND Tiwari's son died under mysterious circumstances.

The Crime Branch was Delhi Police, which was investigating the case after the police registered a case of murder into his death, had taken into custody Apoorva and two house helps for interrogation. Sources said police were looking at Apoorva as the prime suspect in the murder case.

The Crime Branch had questioned Apoorva for over eight hours on Saturday at Rohit Shekhar's residence in South Delhi's Defence Colony area, they said.

A case of murder was registered on Thursday, hours after Tiwari's autopsy report stated that he died of asphyxia due to strangulation. The case was then transferred to the Crime Branch.

Rohit died on April 16 under mysterious circumstances. 

What Rohit Shekhar's mother said about Apoorva

On Sunday, Rohit Shekhar's mother Ujjawla hit out at Apoorva and her parents alleging they had their eyes on his property.

"Apoorva's family wanted to take control of the properties of my both sons -- Siddharth and Rohit -- because this house is nearer to the Supreme Court where Apoorva was practising law," she said.

Refuting rumours that Rohit and Apoorva met in the Supreme Court complex, Ujjawla said that they both had met in Lucknow through a matrimonial website in 2017.

They were seeing each other for a year and later took a break in between. Rohit Shekhar maintained distance from her and said he did not want to marry her, she said.

They were not in touch from January to March, 2018. But on April 2 they came to me and expressed their wish to get married, Ujjwala said.

They also discussed mutual divorce several times and later decided to end their marriage in June, she added.

Ujjwala said Apoorva was also against giving a share of property to son of Rajiv Kumar, a relative and aide of Tiwari.

Apoorva always had issues with Rajiv and his wife, Ujjawla said, adding that reports of Rohit Shekhar having affair with Rajiv's wife is "baseless and false".

"My elder son Siddharth expressed his wish to give a share to Rajiv's son Kartik Raj but Apoorva was disappointed and expressed her displeasure over this," she said.
