Luke Littler warns fans of fake autographs on merchandise: ''I haven't signed much.."

Luke Littler has advised his darts fans that they should be careful about buying ''autographed'' merchandise after 'The Nuke' found out that his merchandise with fake signatures was being sold online.

The English teen sensation has learned that scammers are trying to make money by forging his signature and then selling products to darts fans.

During the Dutch Darts Masters, Littler had an autograph session, with the reigning junior world champion putting his scrawl on an Ultimate Darts Card. In doing so, Littler could be seen simply putting "The Nuke" down on the product. This signature then proved easy for scammers to copy.

"There are a few people out there who will try to steal it (my signature) and say it’s me and that," said Littler.

"I have seen quite a few over the past few weeks after the world championship. People have been privately messaging me saying: ‘Have you signed this, have you signed that?’ No. Sorry to bring it to you, but I haven’t signed much…"
