Thane: Central police on Wednesday arrested two people, a woman and a man with whom she was in a relationship, for killing her other lover on Monday night.

The woman’s husband Mamta Singh alias Babli had died and she was in a relationship with men Ajay Chavan, 40, (victim) and Datta Kasunde (accused). Chavan, a sales executive with a private company, lived with his wife and two children in Ulhasnagar Camp 3.

Police said Babli and Chavan often quarreled over their relationship with Kasunde. On the night of the incident, Babli called Kasunde, who arrived with Mukesh Kasunde and eight others. A heated argument ensued, during which Chavan was attacked with fists, swords, knives and an iron rod. Chavan’s brother Arvind and his family members tried to intervene but were also injured in the attack.

Chavan suffered serious injuries to his chest, head and hand. The police, alerted by locals, found Chavan lying in a pool of blood and rushed him to Ulhasnagar Central Hospital, where he was declared dead on arrival. Babli and Mukesh Kasunde have been arrested and others are being sought.

In another case, a 24-year-old man allegedly stabbed a 23-year-old woman to death after she rejected his marriage proposal in Bhiwandi on Monday, Shanti Nagar police said. The victim’s younger sister was also injured when she tried to intervene and save her sister.

The accused, Raju Mahendra Singh, a security guard, lived with his family in a rented residence in Bhiwandi, where the victim also resided. The two had been in a relationship for four years, both originally from Uttar Pradesh. When the woman rejected his marriage proposal, Singh allegedly stabbed her several times on the night of October 28.

After the attack, he fled the scene. The woman was rushed to a nearby hospital, but was pronounced dead upon arrival. Police have since registered a case of murder.

Two months earlier, the victim’s family found out about the relationship and confronted the duo. Later, Singh went to UP but continued to communicate with her over phone. Singh returned from UP, entered his house and a heated argument ensued which resulted in a fatal incident, police said.

Senior police inspector Vinayak Gaikwad said, “We have formed two teams to arrest the accused and have launched a chase.”
