Two men were severely injured in an explosion inside a house within the Swabrina neighbourhood in Likoni, Mombasa on Sunday night.
According to the police, the duo was assembling a liquid-based improvised device in the kitchen, which later accidentally went off around 10 pm, injuring them.
The two, alongside parents of one of them who escaped later during treatment, were arrested by anti-terror police who rushed to the scene.
The suspects, while bleeding profusely, were first rushed and treated at a private dispensary and then moved to Likoni Hospital. Reports indicate it that at it was at the hospital where one of the suspects vanished from police custody.
The other suspect was treated and released to anti-terror police for further grilling.
The same suspects had earlier been arrested while they were teenagers, during the infamous raid on Musa mosque in Mombasa on February 2, 2014, in which six worshipers and a policeman were killed
"We have received reports one of them was jailed for three years and another four years, and we are investigating that," Likoni OCPD Benjamin Rotich revealed on Monday.
According to Rotich, detectives have not established the materials used to make the explosive or what exactly happened.
He, however, indicated that the parents were detained on suspicion of tampering with the scene by washing away blood stains and carting away some material before the police arrived.
On Monday morning, 20 anti-terrorism police officers, accompanied by General Service Unit (GSU) and intelligence teams, sealed off the site for investigations.
Police have launched investigations following intelligence reports that a terror act, intended for a week prior to the two bombers being nabbed, was disrupted.
