[2] According to the Puranas, Kamsa issued an order for the execution of his own father once he grew paranoid of the valour of Krishna and Balarama in Mathura, observing them slay wild elephants that he had released for their murder.
And wearing your crown of sunny lustre govern the city of Mathura, delightedly with your sons and grand-sons, defeat your enemies and multiply the Bhoja race.
From the thousand jars of gold coins reserved for the citizens of Mathura in that ceremony of installation the king of gods has ordered that one thousand should be given to each of the panegyrists and bards, one hundred to each old man, prostitute and other men and ten thousand to each of the Yadavas, Vikadru and others who live with the king Ugrasena.Samba, the son of Krishna and great-grand son of Ugrasena, had insulted several sages by disguising himself as a pregnant woman and asked the sages to ascertain the baby's gender.
He, along with Bhurshiravas, Shalya, Uttara and his brother Shankha, Vasudeva, Bhuri, Kamsa, joined the company of devas in heaven.
The Vishnu Purana states that the city of Mathura was "well presided over by Ugrasena, and abounded in a happy population both of men and women".
