The public have been warned to be on the alert for a major phone scam that has been ongoing over the past while. The crooks involved are ringing people, who will hear distressed screaming or shouting in the background. The line then goes dead. If the number is called back, it can drain the victim's phone of top-up credit, or add a large fee to the phone bill.
The calls tend to begin with a +247 or +241. Do not answer any calls for these type of numbers, and if answered in error, hang up immediately.
