Gurdial Singh allegedly killed Ranjit Kaur, 55, at their village Rahpur, some 15 km from Hoshiarpur town, after a heated argument.
Police said Gurdial Singh, who hailed from Calgary town in Canada, slit his wife's throat with a sharp weapon Tuesday night. The scuffle left their elder son, Kamaljit, injured.
The couple and their sons reached Punjab March 1 for the wedding of their younger son Gurvinder. The marriage took place March 11. The couple clashed as Gurdial Singh did not invite his in-laws for the wedding.
Family members told police that Kamaljit had lived in Canada for over seven years. His parents and other family members migrated to Canada last year.
