Armed men on Saturday morning raided Mponye Police Post in Kabalagala, a Kampala suburb, and made away with a gun.
The panga-wielding men injured a police constable Dickens Kasozi who was on guard.
Police said Kasozi’s fingers and neck were cut slightly by a panga from one of the attackers before stealing a gun and 30 rounds of ammunition.
The police post’s commander, ASP Emmanuel Kanusu, was out on a patrol operation.
Police Flying Squad has since arrested four men suspected to be part of the gang of five who attacked the police post.
They are; Alex Kamugisha Timothy Lutalo, Meddy Bale and Moses Nyeko.
