The assailants barged into the house of Abhimanyu Lodhi and attacked him with sharp-edged weapons killing him on the spot while his wife, Gita, also received serious injuries and died on way to a hospital in Kanpur, superintendent of police Vinod Kumar Singh said.
The couple's one-year-old son Surjeet was also injured in the incident and has been admitted to Kanpur hospital, the SP said, adding the incident appeared to be related to property dispute.
