One traffic police officer sustained gunshot wounds while another broke his leg as detectives from the Ethics and Anti-Corruption Commission arrested officers allegedly collecting bribes from motorists.
The residents were treated to drama during the early morning incident as gunshots rented the air.
Witnesses told the Standard Digital that chaos began when four officers directing traffic defied orders from the detectives to surrender.
They attempted to flee as one of them cocked his rifle and shot several times at the EACC detectives.
Joseph Opiyo, a conductor of a matatu that had just been stopped by the officers a few meters from where the arrests were made, said that they were shocked by the events.
"One of the police officers jumped into a ditch and broke his leg," said Opiyo.
Locals also chased another officer but he managed to escape.
EACC Regional Deputy Director Aura Chibole confirmed the arrests and said that they were processing the suspects before arraigning them.
"One of their officers accidentally shot a female officer while trying to escape. She has been taken to hospital for treatment," said Aura.
