A competition to win free beer for Father's Day circulating on WhatsApp is a scam, Heineken has said.
The message offers the chance to win one of 5,000 coolers full of lager and links to a fake quiz-style competition.
But Heineken said this was a phishing scam - a way of tricking someone into clicking a malicious link or entering personal information like bank details.
A spokesperson urged anyone who got the message to "delete it immediately". The BBC has contacted WhatsApp for comment.
Heineken's representative added: "We're aware of the current phishing scam circulating through social networks, which is not sanctioned by Heineken. We have alerted the relevant authorities."
