An Improvised Explosive Device (IED) planted at the Kenya Revenue Authority (KRA) offices compound exploded on Thursday evening with no damages reported.
Confirming the 3.45pm incident, Mandera East OCPD Ekai Maruk said the IED was suspected to have targeted police guarding the KRA offices.
"We heard an explosion which was from an IED planted at the KRA offices compound which might have targeted police officers manning the offices, we nabbed one suspect and is helping us with investigations," said Maruk.
He said no one was injured or any property damaged as the police officers were out patrolling the area when the IED went off.
Maruk said the IED might have been used to instill fear in police patrolling the border government's installations that has made the militants operating in Somali's Bula Hawa find it difficult to cross into Kenya and carry out attacks.
"We will not relent in protecting lives and property no matter what as the government has given us enough security officers and equipment to deal with Al-Shabaab menace.
In addition we have a full contingent of 200 GSU officers in addition to KDF to help in enhancing security," he said.
In spite of the closure of the Kenya-Somali border in 2011 by the Kenyan government, Mandera town has experienced a number of attacks from the Al-Shabaab militants with the police blaming it on the porous border and poor equipping of the service.
