The Department of State Services, DSS, has declared wanted one Rufai Tsiga, the suspected mastermind of the bombing of Nyanya Motor Park on April 14 along with an ex-soldier accomplice, Aminu Ogwuche.

Spokeswoman of the DSS, Marilyn Ogar, who made this known at a news conference in Abuja on Monday, also announced a N25 million reward for anyone who can give information that would lead to the arrest of the suspects.

“Rufai Abubakar Tsiga, a Boko Haram leader, is the mastermind of the bombing of April 14, 2014 at El-Rufai Motor Park, Abuja. Tsiga was actively aided by a co-mastermind, Aminu Sadiq Ogwuche, a student of Arabic Language at the International University of Africa, Sudan. The sum of N25 million is hereby announced as reward for anybody with useful information on their whereabouts,” she said.

Ogar also paraded five suspects in connection with the bombings which killed more than 200 people with over 120 others injured.

The suspects paraded are Ahmad Abubakar, 43; Muhammed Ishaq, 30; Yau Saidu, 28; Anas Isah, 22 and Adamu Yusuf, a cleric, 43.

The DSS spokesperson said that on the night of April 13, Tsiga and one Muhammed Ishaq, one of the arrested suspects, moved a vehicle laden with explosives to the Nyanya Park.

She said Ogwuche, a UK-born Nigerian, was a solider with service number SVC 95/104, who served in the Intelligence Unit of the Nigerian Army at Child Avenue, Arakan Barracks, Lagos, between 2001 and 2006 before deserting the army.

She added that Ogwuche was arrested on November 12, 2011 at the Nnamdi Azikiwe International Airport, Abuja, on arrival from the UK for a suspected involvement in terrorism-related activities.

Ogar said he was, however, released on bail to his father, Agene Ogwuche, a retired colonel, on October 15, 2012, following intense pressure from human rights activists, who alleged human rights violation.

Ogar said that the arrested suspects claimed that they bombed the park to retaliate the killing of a Boko Haram member at the park a week before the incident.

Ogar urged the public to be vigilant as terrorist elements were disguising and taking up menial jobs and parading themselves as businessmen daily in Abuja and its environs.
