A police statement released yesterday said the incident occurred on Sunday afternoon at Magomeni when police were conducting routine patrols.
It stated that the suspected bandits were killed during a live exchange of fire with the police.
“Police were conducting patrols in Magomeni but suddenly a group of bandits started to attack and responding to the occurrence, police injured three of them who died when taken for treatment at the Muhimbili National Hospital,” it said.
Police said early investigations shows that the suspected robbers were engaged in a number of crime incidences in Dar es Salaam and neighbouring regions.
Police will continue conducting patrols within the city, the statement affirmed, urging residents to support police efforts by tipping them on likely criminal incidences in specific areas.
Last month, police headquarters spokesman David Misime said that crime went down by two percent between January and November.
He said that crime incidents declined from 54,867 reported in 2018 to 53,685 reported between January and November, last year.
The number of traffic accidents decreased by 26.2 percent as in 2018 there were 3,689 people involved in road accidents compared to 2,722 in a similar situation for eleven months of 2019.
The slim achievements made in controlling accidents and criminal acts were not a cause for celebration by the police, the spokesman affirmed.
"The police are continuing to work hard to make road accidents and criminal acts part of history. We are determined to end these two social evils," he declared.
Up to 75 percent of road accidents were caused by negligence and human error, he said, appealing to motorists to be alert, citing night driving, lack of attention on the wheel, drunk driving, festive seasons as accident prone situations.
