Major Vaibhav Vishal, 30, is posted at the Army's 54th Infantry Division in Secunderabad. He had been admitted to the ICU of an army hospital since his wife Sandhya Singh's death.
On April 18, Major Vishal reportedly found his wife hanging from a ceiling fan at their army accommodation. The same night, he claimed chest pain and went to the hospital. The police could not question or arrest the officer as he was on army premises. He had reportedly told them that he was sleeping when his wife hanged herself.
His arrest yesterday was based on a complaint by Sandhya Singh's family that she was harassed for dowry. A case of suicide was registered initially, but his name was added after Sandhya Singh's sister Uma, who works in Ghaziabad near Delhi, alleged that she was harassed by her husband and his family.
On Wednesday, Major Vaibhav Vishal was handed over by the army to the local police and later arrested. He has been sent to 14-day custody.
The police have reportedly found evidence of dowry harassment and are now looking for Major Vishal's mother Asha Singh and sister Khushi.
The couple, both from Uttar Pradesh, fell in love and married around two years ago. They moved to Hyderabad in November.
Sandhya Singh left no suicide note. She worked for Radio Charminar and had organized a "musical nite" just a day before her death. Her colleagues have reportedly told the police that while she had shared she had problems, she didn't seem depressed.
