The Nedumbassery Police on Tuesday night arrested a 38-year-old man for murdering his intellectually disabled mother after brutally assaulting her at their rented home in Chengamanad. The accused, Binu, an electrician, was arrested following an investigation prompted by the post-mortem findings. He was produced before a court in Angamaly and remanded to custody on Wednesday.

Binu took his mother, Anitha (58), to the Government Hospital, Aluva, saying she had been found lying next to the washing stone at their house. Preliminary checks revealed multiple wounds and bruises on her body. The post-mortem later confirmed deep injuries and internal bleeding, indicating she had been brutally assaulted before her death.

"According to initial information, the woman had been undergoing treatment for mental illness at a hospital for the past 20 years. She was reportedly discharged forcibly and brought home by her son three months ago," a police officer said. During detailed interrogation, Binu confessed to the crime, the officer added.

Police suspect the murder may have been motivated by a desire to gain ownership of a property registered in the woman’s name. An investigation is underway.
