Local officials told reporters that one other police officer and a passer-by were injured in the blast in Makhachkala, the republic's capital.
Earlier, Russian media reported that security officials defused a bomb in the city center, one day after a member of the local parliament was murdered.
Zubair Tataev, who was also director of the Khasavyurt branch of the regional natural gas company Daggaz, was shot dead late on 4 July while traveling by car near Dagestan's border with Chechnya.
Tataev's uncle, Ibragim Tutushev, was in the car and also killed.
The unrest comes after 10 Russian soldiers were killed last week by a powerful bomb blast in Makhachkala.
