The deceased has been identified as Madhu, a resident of Rajakkad in this hill district.

According to police, the incident occurred on the evening of August 15, when Madhu's son, Sudheesh, aged 35, allegedly returned home intoxicated and began assaulting his mother.

When Madhu intervened, he was allegedly attacked by Sudheesh, a police officer said.

Madhu, who was initially found unconscious on the roadside by neighbours, was rushed to a private hospital in Rajakkad, police said.

He was later shifted to a hospital in Thodupuzha as his condition worsened due to serious injuries. Madhu's wife, who suffered minor injuries, was later discharged from hospital.
