British police seized 20.21 BTC alongside other cryptocurrencies and bank funds worth about $1.4 million after tracing the assets to darknet markets that operated between 2016 and 2019. Investigators said the individual connected to the funds had a prior money laundering conviction and has since died. Police said the now-shuttered dark web platforms were used for crimes including drug supply and human trafficking, but did not identify the specific marketplaces involved. The sites were later shut down by law enforcement.
