Julian’s cousin, George Cadman, wrote on Facebook: "My cousin, Julian Alessandro Cadman is missing. Please like and share.
"We have found Jom (his Mum, my cousin-in-law) and she is in a serious but stable condition in hospital.
"Julian is 7 years old and was out with Jom when they were separated, due to the recent terrorist activity.
"Please share, especially if you have family or friends in Barcelona. Thank you."
