Police in southwest Germany said on Monday that they seized 646 kilos (1,425 pounds) of drugs, including a record 49,500 tabs of LSD, during a raid against a suspected international drug ring earlier this year.

Police seized the drugs, which also included hashish, ecstasy and amphetamines, in January at two separate locations in the state of Rhineland-Palatinate. The LSD haul amounted to Germany's largest ever seizure of the illegal drug.

Prosecutors said the drugs' street value was about €9.8 million (11.4 million dollars).

Swedish origins

German authorities suspected an international drug ring was behind the stash after Swedish police made an earlier haul in mid-2017 that led police to a 33-year-old couple living in Andernach, a small town in northern Rhineland-Palatinate.

Police went on to identify a total of 11 suspects and believe the ring has been active across Europe, smuggling drugs to and from Britain, Belgium, the Netherlands, Norway and Sweden.

During the January raid, police also arrested seven suspects, four of whom had been residing in Rhineland-Palatinate.

Rolf Wissen, a spokesman for the prosecutor's office, said officials had not released information about the haul until now because the investigation is still ongoing.
