This confirms prosecutor Elisabeth Anderson to TT.
She does not want to disclose how much narcotics were seized.
We are at the beginning of this preliminary investigation and then there is always an extra high level of secrecy.
It was on Thursday that a car with the now detained trio was stopped after a car chase in central Strömstad. The operation involved both the police and the Customs Service.
It was a car that came at high speed with the police and customs behind it. The car drove up onto a gravel heap and got stuck, a witness told Bohusläningen.
Three people, two women and one man in their 20s and 25s, were arrested and later detained over the weekend, suspected of gross narcotics offenses.
According to the prosecutor, it involves a large quantity of narcotics.
The quantity is far above gross offense, but I cannot say how much and what type of narcotics it concerns, says Elisabeth Anderson.
Were they on their way into Norway or did they come from Norway?
I do not want to comment on that either.
The prosecutor does not want to say whether the trio is previously known.
But it is clear that the investigation will be extensive, including analyzes of what was seized.
Then if it will take two months or longer, I cannot say, concludes Elisabeth Anderson.
