Chandraboj (41), Deendayal (30), Subham (18) and Vinod (25) were arrested for killing Dipak and his two accomplices on Thursday for having relationship with a minor girl of their family, Balaghat's Tirodi police station in-charge inspector Harish Yadav told PTI.
"The killings were carried out for honour," he said.
Chandraboj, Deendayal and Subham were arrested yesterday while the fourth accused was nabbed today, Yadav said.
The accused allegedly tricked the victim by sending him an SMS from the girl's phone asking him to meet her at Dhobi Tola area three days ago, police said.
Chandraboj, uncle of the girl was furious after he read some intimate messages sent by Dipak to his niece and thus hatched a plan to kill the youth with the help of other family members, police said.
Further probe in the matter is on, they added.
