Chandigarh, Feb 22 (IANS) It was assumed that depression drove 35-year-old Aruna Srivastava to suicide here four days ago. But now her husband has been arrested for allegedly abetting the suicide after a note was found written on her thigh.

Aruna's husband Subhash Chander was arrested late Sunday and has been booked, along with his alleged girlfriend Babita and her brothers, for abetment to suicide, a police official said Monday.

According to the police, Aruna was found hanging in her home in Sector 41 by her 11-year-old son Ujjwal Feb 18 when he returned from school. The boy even cut the rope in a failed bid to save his mother.

At that time, police did not find any suicide note and during questioning, her husband Chander, who was out of town that day, told the police that Aruna was under depression.

But after the post-mortem examination, doctors revealed that a suicide note was written on Aruna's left thigh, the official said.

In the note, Aruna had written that her husband Chander, his girlfriend Babita and her brothers Pappu and Anil are responsible for her suicide. Babita and her brothers live in Allahabad, police said.

'On the complaint of Aruna's father Ashwani Kumar, we have booked all the four for abetting Aruna's suicide. Chander has been arrested and now we are trying to nab the other accused,' said Janak Rana, the investigating officer of the case.

Chander is a Punjab government employee and his family had shifted here from Allahabad two years ago.

While searching Aruna's house, police also recovered some photographs showing injury marks on different parts of the body.

Aruna's family members claim these are Aruna's photographs that she had kept as proof against Chander.

'We are still trying to verify the authenticity of these photographs,' Rana said.
