Chidiebere Justice Mark -- known as JusticeCrack to his more than 623,000 followers on TikTok and Instagram -- posted two videos on his social media accounts last month showing screenshots of chats he said he had with troops serving in Maiduguri.

The northeastern city is the capital of Borno state, the epicentre of a 17-year jihadist insurgency.

One of the videos shows a small portion of rice in a plastic bowl, along with sachets of powdered milk and chocolate, a piece of meat, one egg and small bowl of soup, which he described as "vomit".

Soldiers have complained in the past over poor conditions and equipment in a conflict that has dragged on for nearly two decades.

The influencer said the photos featured in the videos were sent to him by serving troops.

In a court document dated Monday and sent to AFP on Tuesday, lawyers for the Department of State Services (DSS) described the content of the videos as "false" and alleged they were "likely to cause fear and breach of peace".

The charges include posting a video "for the purpose of causing annoyance, ill will and hatred".

The army said at the weekend, after Mark was arrested, that the soldiers who chatted with him were in its "custody".

Spokeswoman Appolonia Anele said Mark "seemed to be inciting soldiers to create discontent".

Nigeria's jihadist insurgency has killed more than 40,000 people and displaced around two million in the northeast since it erupted in 2009, according to United Nations figures.
