Tirupathamma hit her husband Ravula Sampath by a pestle last night at their residence, nearly 50 kms from here, Huzurabad Deputy Superintendent of Police M Ravinder Reddy told reporters.
Sampath, a washer-man, was habitual drinker and he allegedly tried to outrage the modesty of his 16-year-old daughter on several occasions, he said.
He also allegedly harassed Tirupathamma. Enraged over his behaviour, she attacked him when he was in an inebriated state after an altercation. Sampath died on the spot, the officer said.
Following a complaint, a case under relevant sections of IPC was registered and investigations are underway. However, no arrests have been made so far, police said.
