It was during a routine check of the truck on the E4 that customs officials made the discovery last week. In a maple compartment, a larger amount of narcotics was found, according to the customs incident report.

The two customs officers requested immediate reinforcements from colleagues and police, which took 15-20 minutes.

The report states that there was deemed to be an imminent risk of a possible release attempt. When the reinforcements were in place, the checkpoint on Västerleden was cordoned off for other road users.

Car circulated the place

During the check, a passenger car was noticed which, according to the report, belonged to a person with links to one of the larger criminal networks in Stockholm's suburbs.

Customs describes how they had to stand at the checkpoint for a long time while waiting for salvage, and the car in question must have circulated the checkpoint throughout the time.

Missing armament

In the report to the Swedish Work Environment Authority, the customs officers believe that they were in a very vulnerable position as they lacked armament other than batons and pepper spray.

"During the inspection until the salvage began, it was with a lump in the stomach and great concern and fear for everyone's life and health that we stood COMPLETELY exposed and totally unable to defend ourselves, with the protective equipment that Swedish Customs considers sufficient for the task, against anyone who wanted to take back the goods found in the truck," writes an official at customs to the Swedish Work Environment Authority.

During the transport, the police authority decided on reinforcement weapons for the police officers who would participate.

SVT is seeking Swedish Customs for a comment.

Two people have been detained after the seizure on suspicion of extremely serious narcotics offences. They deny any wrongdoing.
