They said the couple, who got married in 2008, were on the verge of separation. The man had moved to Delhi and found a job there and planned to buy a flat in Whitefield here, for which he wanted his wife to be a co-applicant for a home loan.
On November 12, Siddarth Choudhary flew down from Delhi and tried to persuade wife Ruthi to be a co-applicant, but she refused. A heated argument ensued following which he stabbed her to death and cut his veins with a knife, police said.
The couple's three-year-old daughter and the woman's mother were at home during the time, police said.
The lady informed her second daughter, staying in another part of the city, who contacted police. They rushed to the spot and arrested Siddarth after administering him first aid
