Heavily armed police stormed an apartment in the city’s Angered district before apprehending two men suspected of involvement in the shooting in Stenungsund earlier in the day.
The shooting occurred in an apartment in Stora Höga in Stenungsund and police were called to the scene at 12.15pm.
Police refused to comment on media speculation that the killings had links to organized crime. Local newspaper Göteborgs-Posten said the car used to flee the scene of the crime was a BMW regularly used by a man with ties to Hells Angels support crew Red & White.
Police confirmed they had fired shots at the vehicle’s tyres in the course of the chase.
A woman in a house near the crime scene told news agency TT that there had been a knock on her door at around 12 o’clock.
“It was a woman who said she’d been cleaning in the building. She was in complete shock and came running in her bare feet.
“She said she had climbed over one of the bodies and wanted us to call the police. She wanted it done quickly because she said that one of them was maybe still alive.”
Police have launched an investigation into the attack but have yet to establish a motive for the killings.
