More infoA grandad suffered a shock heart attack on holiday in Tenerife - leaving his family facing medical bills totalling €36,000. Delivery driver John Lockyer Drury was in his 'favourite place' with his wife Lisa when he became seriously ill in September. "On the Sunday night, he collapsed with a heart attack. He had a blocked artery - that's what caused the heart attack, not the asthma. "We appreciate the seriousness of the situation and are closely monitoring the case and we will continue to support Mrs Lockyer Drury."
