Mr El-Rufai’s mother died on Friday in Egypt.
“I am going to find you (it’s easier than you think) & unalive you and your family,” Bashir El-Rufai threatened an X user.
Former Governor Nasir El-Rufai, an estranged ally of President Bola Tinubu, has recently been excoriating the ruling party and the government.
Many netizens have condemned the act, labelling it insider trading.
“Even IMF & World Bank no go save una that time,’’ said Mr El-Rufai.
This move validates rumours that Mr Sani and former Governor Nasir El-Rufai’s feud had further deepened than anticipated.
Otosirieze Obi-Young left Brittle Paper in April after publishing a story about how Bashir El-Rufai threatened to organise a gang-rape of a Twitter user’s mother.
