The police were called to an incident in Rinkeby on Friday night at around 10pm. When they entered a café, they found the two men dead and a third with non-life threatening injuries.
The police do not yet know how many suspects they are looking for but have “theories” about why someone would want to kill the men, TT news agency reported.
Witnesses in the area said they saw a white car with black tinted windows leaving the scene, TT reported. The police seized a car in the area on Saturday morning, but did not specify whether it matched that description.
Police figures show that people killed in shootings have been increasing in recent years, with 31 killed in 2015.
