A 28-year-old man allegedly committed suicide after bludgeoning his lover to death with a boulder at Marasur Gate near Anekal on Thursday.

The man has been identified as Kiran from Marasur Gate, who is a native of Tamil Nadu. The police said he was a manager with the electronics division of HAL. He took Anu, also a resident of Marasur Gate and a native of Kerala, to an open area near his house and murdered her. Anu was married to Govinda Raju when she began a relationship with Kiran.

The police suspect friction between them, which led to the murder.
