Messages have been flying around Facebook warning users about a potential hacker called Jayden K Smith, saying you should not accept his "friend request".

But users have nothing to fear - the message is a hoax and as far as we can tell Jayden K Smith does not exist.

The message says, "Please tell all the contacts in your messenger list not to accept Jayden K. Smith friendship request. [sic]

"He is a hacker and has the system connected to your Facebook account. If one of your contacts accepts it, you will also be hacked, so make sure that all your friends know it. Thanks. Forwarded as received."
