Astrakhan police have identified and placed on a wanted list three men suspected of a string of assaults on local cops that left three officers dead this summer, Interfax reported Monday.
Police did not release the suspects' names but said two of them are brothers from Kazakhstan, aged 36 and 38, and the third is a 20-year-old ethnic Tatar. All three are residents of the Astrakhan region.
The suspects were filmed by surveillance cameras in a city park where they staged their first attack, the report said. Investigators have also confirmed that the same guns were used in two of the three attacks.
Police are on the lookout for suspects, whose facial composites have been published online.
A patrol officer was stabbed to death and another was wounded in a city park July 27 by three assailants who took away their service guns.
Another police officer was gunned down in the city the next day while attempting to check documents.
On Aug. 29, three police officers were shot and wounded while chasing a car without license plates.
