Action Fraud has become the latest organisation to be cloned by scammers.
The organisation, which is the UK's national fraud and cyber reporting centre and is run by City of London Police, has warned of a fake Twitter account pretending to be the real deal.
Action Fraud, whose Twitter handle is @actionfrauduk, warned that the fake account was @action_fraud_uk and that consumers should be careful.
A spokesman for Action Fraud said: "They are asking for personal information and hijacking conversations. This account is not verified; do not send them any information. We are working on getting them shut down."
The fake account has tweeted 13 times but has more than 3,200 followers.
Last month the Financial Services Compensation Scheme warned about a Russian website claiming to represent it.
Under the banner of Investor Protection Management, the site by Insider Group claimed to be a wholly-owned subsidiary of the UK compensation scheme.
This was not the first attempt scammers had made at pretending to be the FSCS.
In September the scheme warned consumers of fake emails from fraudsters claiming to represent it.
In January there was another attempt at impersonating the FSCS when scammers posing as the scheme emailed consumers in a bid to entice them into providing personal information with the promise of a $5.7m (£4.3m) payment.
