Police in Garissa have launched investigations following Monday night's attack of a police vehicle patrolling the Ndogo suburb at the town.
The incident that took place at around 7.20 pm left six administration police officers injured by gun and grenade attacks. Four of them were treated and discharged while two are still nursing their injuries
According to Geoffrey Lekiloi, one of the injured police officer admitted at Garissa Provincial Hospital, the vehicle was ambushed after it slowed down to navigate a sharp corner.
He said two grenades were hurled into the vehicle as the gang shot at them.
He said in the ensuing shoot out, a woman at a nearby kiosk was shot and a pedestrian killed by stray bullets.
Garissa OCPD George Losku said investigations are ongoing and promised residents a probe into the identity of the slain man saying a controversy had emerged over his killing.
Losku said one of the police officers who had shrapnel's lobbed in his stomach was set to be airlifted to Nairobi for further treatment.
The incident targeting security officers is the first this year. Late last year, three people were killed in Garissa town by unknown assailants and there have been no arrests made to date.
During last year's Jamhuri Day celebrations, County Commissioner Mohamed Maalim said they have information militants are targeting security officers.
He said the bounty is Sh800,000 for each eliminated head and the reward could go higher depending on the security officer's rank.
