Yasin Abdullahi, who goes by the name Yasin Byn, is currently leading the chart with XO, a song which lauds the intoxicating combination of Rémy Martin cognac and cannabis.
According to the Expressen newspaper, he was arrested on the night before New Years' Eve, after a 20-year-old young man was found by with fatal shot wounds to the head in the Stockholm suburb of Rinkeby. The man, formerly a close friend of Yasin, died later that night.
The rapper has won more than 640,000 monthly listeners on Spotify for songs glorifying his life of drugs, violence and gang crime, which have been played more than 50m times.
He is believed to combine his successful musical career with the leadership of Shottaz, a gang based in the Stockholm suburb of Rinkeby. In one rap, he boasts about his handling illegal weapons: ”If I'm sitting in a car. At least two Glocks in the back. Yasin Byn is hard to kill.”
Abdullahi is one of a total of seven young men arrested in connection with the case. Two were released quickly, two were released after a custody hearing on Friday, and three, including Abdullahi, remain held on suspicion of murder.
Frida Wallin, Abdullahi's defence lawyer told Expressen she had no comments to give on how her client planned to plead.
Shottaz is currently involved in a bitter four-year gang war with its local rival Dödspatrullen (the death patrol), a gang war which was involved in the shooting of a double killing in Copenhagen last July.
Abdullahi has been sentenced three times for drugs offences since 2015, and was in 2018 sentenced to prison for two years and three months after he was stopped by police in a car in the Stockholm suburb of Bromma, together with the victim of his current murder case, carrying a submachine gun and a semi-automatic pistol.
As well as XO, Abdullahi has three other songs in the Spotify top 50 list.
