The true identity of Caleb Milligan on Emmerdale has had fans puzzled after bosses confirmed he is hiding a secret.
Caleb was introduced to viewers as the long lost brother of Cain Dingle, with him keen to connect with his sibling now he was in prison. The pair fell out years ago, and Caleb came back to quiz his brother on why he lied about Faith Dingle's death.
However, some fans of the ITV soap are convinced Caleb isn't who he said he is - and theories have so far included that he is an undercover police officer, related to other village residents or he's working to bring Kim Tate down.
