Deputy Commissioner of Police (West) Sharad Aggarwal said Kaur made duplicate keys of all doors in her husband’s house and gave them to Puneet. Their plan laid out, she reportedly returned to the house on Wednesday and let Puneet in sometime during the night.
The two overpowered Singh while he was sleeping and Puneet stabbed him — there were multiple stab wounds.
Puneet worked with his father in their business of readymade garments in Karol Bagh, the police said.
