Suspecting that an injection given by a doctor was the reason for his HIV infection, a 35-year-old Satara resident attacked the doctor when the latter visited his parlour, killing him.
Sachin Gaikwad, who has been arrested, owns a gents' parlour in Pingali village in Satara district, where Dr Ajit Jagdale (BAMS) was a medical practitioner.
According to the police, Jagdale, 27, had treated him with an injection for some ailment in the past, which later led to a painful lump.
When Gaikwad got himself examined at another hospital in Satara, he was advised removal of the lump and blood examination.
The examination indicated HIV infection, which Gaikwad suspected was caused by the injection administered by Jagdale.
On April 12, when the doctor came to his parlour for a shave, Gaikwad attacked him with a sharp weapon, seriously injuring him.
The doctor, who incidentally got married three days prior to the incident, succumbed to his injuries while undergoing treatment at the hospital.
Gaikwad, who fled the spot of the crime, confessed to the crime when he was arrested, police said. He has been remanded in police custody till April 15 by the magistrate court.
A mob of enraged villagers attacked the parlour, destroyed the furniture and other materials, and were advancing to set Gaikwad's house on fire when the police intervened and prevented further violence.
