The desperate mother of a missing 23-year-old said she feels she's "dying inside" since her son disappeared four days ago.
Antonino Coppola, 23, has been missing since September 16 in a disappearance that his family said is "out of character".
Antonino, who was supposed to start his new waitering job today, was on the tube with a friend when he reported having a stomach pain and had to get off.
CCTV footage shows Antonino, who has been in London for almost three years, exiting Bow Road tube station in east London in search for a bathroom.
His friend, who was new to London and relied on Antonino's guidance to get around, waited for him at the station but he never returned.
Family and friends of the former assistant manager from Positano, Italy, have become increasingly concerned over his welfare as he hasn't been seen since.
His mum, Maria Russo, told the Mirror she hopes her son is found "as soon as possible" as she pleaded with anyone who may have information to come forward and assist police with their inquiries.
"I am worried to death. I am speaking now for my son's sake as we need to find him, but I can't even talk to other people about it because of how much it hurts, I feel like I'm dying."
Mrs Russo said her son's behaviour is odd as they always had a very "honest" relationship which meant she was informed about his whereabouts.
"He used to call me even twice a day, he is really affectionate, and he would never have left his friend alone at the station with his suitcase knowing that he didn't know where he had to go."
