Input: Question: What is the official language of the country wher BCCi Bank is registered? Passage:The BCCI Bank was a Luxembourg-registered bank that collapsed in 1992. It was discovered by the bank's auditors, that the bank was running on loss for many years. It was reported that the bank was involved in drug-trafficking, money-laundering and phony loans. The key player in the collapse was Pakistani shipping magnate Abbas Gokal. It was discovered that Gokal's company, Gulf Shipping Lines, had gotten a US$1.2 billion unsecured loan from the bank. When the bank collapsed and the scandal emerged, Gokal escaped to Pakistan. It was hard to get him because the United Kingdom and Pakistan had no extradition treaty. Gokal was making a trip to America in 1994. When his plane stopped for re-fueling in Frankfurt, German police arrested him and extradited him to the United Kingdom. He was handed a 14-year sentence as a result of the SFO prosecution, the longest sentence handed out in a British court for fraud.
