The provided sources, including high-authority news outlets like the South China Morning Post (SCMP), NHK, and The Independent, consistently and credibly confirm the core elements of the statement: a major robbery involving ¥1 billion in cash did occur in Hong Kong, and it was directly related to a currency exchange business. Multiple reports detail the amount stolen and the subsequent arrest of 15 suspects. However, there is a crucial nuance that makes the statement slightly imprecise. Several of the most detailed sources clarify that the robbery did not occur inside the currency exchange itself. Instead, individuals carrying the cash in suitcases were ambushed and robbed while they were on their way to the exchange shop. Therefore, the statement that the 'currency exchange... was robbed' is technically inaccurate. The robbery targeted people associated with the exchange, not the physical premises. Because the event is real and all other key details (location, amount, connection to a currency exchange) are correct, the statement is assessed as 'likely_true', but its truth probability is reduced from 1.0 to reflect this important inaccuracy.
