Three men stabbed a couple to death here over an old enmity, police said on Wednesday.
Harpal Saini (50) and his wife Koshal (48) were returning from the Muzaffarnagar court to Khalwada village when three men on a bike dragged them from an e-rickshaw and killed them, they said.
Harpal Saini and his two sons Rahul and Shubham were arrested in June last year for killing a resident of Johra village, they said. Saini was out on bail while her sons were in jail.
A case has been registered and four teams have been formed to arrest them, the police official said.
