State Revenue Service (SRS) Customs officer Eddijs Ceipe said the haul was worth between 8 and 12 million euros and most probably originated in North Africa, possibly Morocco.
Flanked by armed guards in balaclavas, the sheer size of the haul was remarkable and weighed in at 1,115 kilos.
The drugs were hidden under citrus fruits and the accompanying paperwork suggested a harmless shipment of fruit rather than enough hash to fuel a good-sized hippie festival for a week.
The load was intercepted not at the border but in Riga, Ceipe said, without giving further details other than the fact that eight Latvian suspects are being investigated, two of which are still being searched for.
If convicted, those responsible could face up to 12 years in jail.
