The family of Pune realtor Ketan Agarwal, who was allegedly murdered by his fiancée Siya Goyal and her lover Chetan Chaudhary, held a candlelight march demanding justice.
Ketan's grandfather Devichand Agarwal accused those close to the family of betrayal and sought capital punishment for Siya and Chetan.
He also believed that Siya was pressured by her family to get married to Ketan, who was set to marry her in November.
The couple were scheduled to get married in a grand Udaipur wedding in a few months.
Ketan's family members led a march, organised at the Belmondo Society in Gahunje on the outskirts of Pune where Ketan lived.
Siya Goyal's parents and brother were questioned by the Pune Rural Police for more than 10 hours as part of the investigation into the alleged murder.
