A dysfunctional marriage ended in the husband hanging himself at his house in Mahalakshmi Layout on Tuesday night.
Madhukiran (36), businessman and father of an eight-year-old girl, had been married for 10 years.
The couple used to fight often and had even been counselled by the police earlier.
Madhukiran did not have a regular source of income and to make ends meet, his wife started working. Madhukiran was opposed to this and the couple frequently fought over it.
On Tuesday night also, Madhukiran came home late and quarrelled with his wife. He then locked himself in the bedroom and hanged himself, preliminary enquiries by the Mahalakshmi Layout police revealed.
