Teenager Alex Batty has said the worst thing about the six years he was missing abroad was “not having a proper education”, according to reports. Speaking to the Sun newspaper, the 17-year-old said he must have read the Harry Potter books “at least 20 times” and his main pastime was reading as he could rarely access wifi. Alex’s grandmother told the newspaper that his mother and grandfather “completely and utterly betrayed me and left me heartbroken”. Greater Manchester police (GMP) say they have launched an investigation into the alleged abduction of Batty, a 17-year-old who went missing while on holiday in Spain at the age of 11. Police officers have interviewed the teenager, from Oldham, who was found walking in France, as part of efforts to establish whether he was abducted. The boy’s image filled newspaper pages after he was reported missing by his grandmother and legal guardian Susan Caruana six years ago when he did not return from a prearranged trip. She believed his mother and grandfather David had taken him to live with a spiritual community in Morocco. Alex was picked up by Fabien Accidini, a chiropody student, near the French city of Toulouse in the early hours of Wednesday last week after walking 22 miles (35km) in two days. Speaking about his time abroad, the teenager told the Sun newspaper: “I had a Harry Potter box set. I’m obsessed with it and must have read each of the books at least 20 times. “I carried it everywhere, even though it was massive and took up so much space. “They’re amazing books. My main pastime was reading because most of the places we were we couldn’t get wifi. I tried to get as many as I could but it was bloody difficult.” He added: “During all my time away I never attended school for a single day. “The only qualifications I have are my Sats test results from primary school, when I lived back in Oldham. “That’s one of the worst things that’s happened to me throughout all this – not having a proper education.” Alex’s grandmother Susan Caruana, 68, told the Sun she overheard the teenager’s mother say they were getting rid of their phones. She said: “They completely and utterly betrayed me and left me heartbroken. “I knew as soon as I heard her say: ‘We’re getting rid of the phones now.’ I thought: ‘I’ll never see him again.’” She added: “During the whole six years I never knew if they were alive or dead. “Every time there was some sort of disaster I feared that he could be a victim.” After being looked after by the French authorities, Alex met his step-grandfather at Toulouse airport on Saturday before boarding a flight to the UK, GMP said. It is thought Alex has been living with his mother and grandfather, who took him to Spain in September 2017, across Spain, Morocco and France.
