It listed the six conditions in a post via its official X handle (formerly known as Twitter) on Tuesday.
The NLC said, first, Chinasa Nwaneri, a special adviser to the Imo governor on special duties who allegedly led the attack on the NLC president and other workers in the state must be arrested and prosecuted.
The union also said all police officers as well as thugs involved in the attack on the labour leader should be arrested, prosecuted and dismissed.
It also demanded the arrest, prosecution and dismissal of the Chief Security Officer in Imo State Government House simply identified as SP Shaba.
“He led, participated and provided cover for thugs to brutalise workers in Imo State,” the NLC alleged.
Another condition given by the labour union was the arrest, persecution and dismissal of an unnamed police area commander who it said supervised the brutalisation of the NLC president and other workers in the state.
The sixth condition for peace was that the former Commissioner of Police in Imo State, Ahmed Barde, must be investigated and prosecuted for his alleged involvement in the assault of the NLC chief.
“Our demands are simple. We want justice,” the group wrote in the X post.
