    Create a fraud detection function that examines a customer transaction history and identifies all transactions exceeding a specified dollar threshold for further investigation. The function should accept a mapping of customer IDs to their transaction amounts and a minimum suspicious amount threshold, returning only those transactions that meet or exceed the threshold value. The filtered results will be used by the bank's fraud analysis team to investigate potential unauthorized or suspicious activities.
