The Euro 2016 football tournament may be drawing to a close, but Asian authorities aren’t letting up in their quest to stamp out illegal online betting.

Just hours before Portugal ended Wales’ fairytale run at the UEFA title, Hong Kong authorities raided a number of locations across the city, breaking up five different bookmaking operations, arresting 19 individuals and confiscating more than HKD 400m (US $51.5m) in illegal wagers.

The single largest seizure resulted in HKD 250m confiscated from a 33-year-old man working out of a public housing flat. The operation had reportedly been accepting illegal wagers for several months and a source told the South China Morning Post that the numbers had “soared by several fold” ahead of the Euro 2016 semi-final matches.

A separate raid turned up betting records worth HKD 100m and HKD 410k in cash. Authorities suspected this operation, which had been taking wagers for the past six months, had links to the infamous 14K triad.
