Mr Abie’s former ally, Mr Jawar, has criticized the Nobel laureate for not doing enough to address the long-standing grievances of the Oromo people, the group they both belong to.
As part of this week’s Economist Opinion, Mr Abe said those who opposed his reforms were sowing the seeds of inter-ethnic and inter-religious divisions and hatred.
A number of other critics, some of whom are not in the country, have been named for being in the group of suspects.
He has also been charged under the Telecom Fraud and Firearms Act, according to a statement posted on social media by the Attorney General.
Rights groups have criticized the fact that it has taken weeks to bring charges against them.
In June, at least 166 people died in the days following the killing of Hachalu, 34.
Father-Ben was seen as a hero in Oromia. His songs focused on the rights of the country’s Oromo people, Ethiopia’s largest ethnic group, and became the national anthem in a wave of protests that led to the fall of the previous prime minister in 2018.
The purpose is not clear. Hachalu said he had received death threats.
