Bengaluru, 2 Apr 

A 29-year-old tech professional has allegedly died by suicide after her 11-month-old son was suspected to have accidentally drowned in a bucket of water at their residence here, police said on Thursday.

The incident occurred on 1 April within the limits of the Chandra layout Police Station, they said.

Police said a letter written in English by the woman was found near the bed, in which she stated that their son had fallen into water and died and that she could not save him, and sought forgiveness.

The matter came to light after the woman's husband, Mahantesh Wali, an engineer, filed a complaint with the police, officials said.

The couple had been living in a rented house for the past four years, and they had a 11-month-old son, Agasthya, they added.

According to the complaint, Pratibha Wali was employed at a tech company near Silk Board and had been working from home.

On 1 April, at around 9am, Mahantesh left for work while his wife and child remained at home. At around 6.30pm, when he returned and knocked on the door, there was no response. He tried calling his wife on her mobile phone, but she did not answer.

He then retrieved a spare key kept near a window, opened the door and entered the house. On checking the room, he found his wife had allegedly hanged herself by tying a saree to a cradle hook. He also noticed a cut on her left wrist and blood stains, a senior police officer said.

Their son Agasthya was found lying on the bed, and when he checked, the child was also dead, the officer said.

An empty strip of 15 tablets was also recovered from the spot, and it is suspected that the woman may have consumed the tablets, police said.

Prima facie, it appears that the infant strayed into the bathroom and fell into a bucket filled with water while the woman was away, seemingly gone to the terrace to dry the clothes. It appears that the woman, distressed over the death of her son, died by suicide, police said.

However, the husband has expressed suspicion regarding the deaths and sought legal action. Further investigation is underway, police added.
