A 30-year-old Beit Bridge man, Philemon Verera, allegedly killed himself by drinking pesticide at his in-laws' homestead, in protest over being denied conjugal rights by his estranged wife.
He allegedly collapsed and died after he gulped a bottle of pesticide, used in the cotton fields.
Local police spokesperson, Insp Tineyi Matake said Verera's body was taken to the local hospital mortuary for a post-mortem to be conducted.
It is alleged that Verera and his wife had a heated dispute at their matrimonial home in Beit Bridge last Wednesday.
Suicide cases are on the increase in the border town. Last month, a 31-year-old Beit Bridge man from Makhado village stabbed his wife and tried to kill his two-day-old baby, before committing suicide following a domestic dispute.
