Phone calls purporting to be from police that ask people to call a particular number are a scam, authorities have warned.
The gendarmerie issued the warning over so-called ‘ping calls’, which are often messages intended to convince victims to call a premium-rate phone line based in Mali.
“If you receive a call on your fixed or mobile phone trying to sell you a particular product, or if you are asked to call back an unknown number, you are the victim of a ping call,” warned the police.
“Never call back an unknown number,” gendarmes said. They added that people can ask their phone-line operator to remove their number from the publicly available phone lists and at the same time register on bloctel here http://www.bloctel.gouv.fr
If you receive an unsolicited message, you can also send an SMS with the one-word message “spamvocal” to 33700 or connect to the site https://www.33700.fr/
