At 8pm police stopped a car near the club’s premises on the outskirts of the city. The driver was suspected of drug offences and arrested.
A decision was then taken to raid the club, leading to seven further drug-related arrests.
“The quantity of narcotics is at an average level,” police spokesman Jan-Peter Larsson told Expressen.
The Diablos, a support group for the Bandidos, have received visits from the police on numerous occasions. Last year, police found loaded weapons at the home of the group’s leaeder.
