The suspect was caught near the Buhari bomb blast site.
The Nigerian military on Friday said it arrested a suspected bomber who disguised himself as a woman.
A statement by the Defence Headquarters said the man who was dressed like woman was suspected to be connected with the explosion targeted at the convoy of a former military head of state, Mohammed Buhari, in Kaduna.
The attack occurred near the busy Kawo market in Kaduna, killing 15 people, the police said.
A bomb-laden car rammed into the ex-leader’s convoy after trailing it for a distance, and unsuccessfully trying to overtake the escort vehicle to reach Mr. Buhari’s armoured SUV.
Some youth in the area tried to lynch the suspect while he was being arrested but were restrained by troops who whisked him away in an Armoured Personnel Carrier, APC.
The statement said the suspect was currently being interrogated by security agencies to figure out his links with the attempt on Mr. Buhari’s life.
