Berhampur: Police Sunday arrested a 22-year-old man for allegedly killing his cousin brother in Ganjam district, officials said.
The deceased was identified as Rajdip Sahu (19), a resident of the Polasara police station area of the district.

An investigation into the incident is underway, said Kaushik Majhi, inspector-in-charge of Polasara police station.
The accused, along with two others, allegedly strangulated Sahu to death, police said.

The body was recovered and handed over to family members after a post-mortem examination.
Search is underway to trace the other accused, he added.
