The Federal Government on Tuesday arraigned Tukur Mamu, spokesman of Islamic cleric Sheikh Ahmad Gumi on a 10-count charge bordering on terrorism financing among others.
He was arraigned before Justice Inyang Ekwo of a Federal High Court, Abuja.
Mamu pleaded not guilty to the charges.
Justice Nkeonye Maha of a sister court on September 13, 2022, gave the Department of State Services (DSS) the go-ahead to detain Mamu for 60 days to enable it conclude its investigation.
Mamu led the negotiation with some terrorists for the release of the Abuja-Kaduna train passengers kidnapped in March 2022.

Mamu is accused of receiving ransom payments including $120,000 on behalf of Boko Haram from families of hostages (victims) of the Abuja/Kaduna train attack.
He is also accused of exchanging voice communications in relation to acts of terrorism with one Baba Adamu, a Boko Haram spokesperson.
The Federal Government also accused Mamu of dealing in terrorist funds in the sum of $300,000 found in his possession.
