A 25-year-old man has been detained, suspected of the murder at Örebro mosque in the Vivalla district on Friday.
The man is suspected of murder on probable cause.
He denies the crime, says prosecutor Mats Ihlbom.
The shooting drama occurred in connection with the Friday prayer at the mosque. A man in his 25s was shot dead outdoors and another man was injured. According to the police, there is no connection to the mosque, but rather to organized crime.
Three more people are being held on suspicion of involvement in the murder.
At least two of them will be requested to be detained on Thursday afternoon.
One of them is suspected of murder and one is suspected of aiding murder, says Mats Ihlbom.
