Inspector General of Police Joseph Boinnet said in a statement one officers succumbed to injuries while four others are currently undergoing treatment in Nairobi, where they were airlifted to.
During the incident, four police vehicles were damaged but police say two of them have since been towed for repairs.
Following a joint operation by police officers and the military, Boinnet assured the country that the situation had been contained even as they pursued the attackers.
“The KDF and NPS are now in control of the situation and a massive operation is ongoing,” he assured. “I want to further say that no life of civilian population has been negatively affected in any way.”
He appealed the members of the public to offer any information that may lead to their whereabouts as the operation continues to weed out the criminals.
The Inspector General also cautioned against using social media to post reports “which is unverified or untruthful.”
Anxiety reigned in Tuesday morning after the public learnt of the attack after police thwarted another attack in the same area a few days ago.
