In a suspected case of honour, a man along with his servant allegedly killed a 30-year-old man, who was involved in a relationship with his sister, and dumped his body in Vasai creek here.

Ganesh (30), hailing from Bihar, reportedly had an affair with the sister of Rajesh Koli in Thane's Bhayander township. Koli had warned Ganesh earlier to discontinue the affair but in vain, Bhayander police station inspector Bhaskar Pukle said.
