text: Conrad Clitheroe, left, and Gary Cooper, right, were thrown in jail after being arrested for writing down aircraft registration numbers in Dubai . A planespotter held with two friends in an Abu Dhabi jail has run out of medicine for his serious heart condition. Conrad Clitheroe, from Stockport, is in a cell with friends Gary Cooper and Neil Munro - also from Greater Manchester. But the 54-year-old's wife says he has now run out of a blood pressure medication - and claims guards 'don't care'. None of the men have been charged with any offence since they were transferred there from Dubai. They were arrested in February at Fujairah Airport over claims they were a 'threat to national security'. They were placed in a cell on February 21, missing their flight home the next day. A judge has since extended their custody licence, which will be up again on April 12. The families of Mr Clitheroe and Mr Cooper have paid £9,000 for lawyer Naseer Hashem – but claim he has been out of touch. Mr Clitheroe's wife Valerie said: 'We haven't been able to get him for a week. The Prime Minister's office has replied saying there is nothing they can do to help. 'I only speak to Conrad once a week now – he's said he's run out of blood pressure medication but the guards don't care. 'I've asked the consulate to help but I'm worried.' The couple were planning to spend Easter in Spain. Now Mrs Clitheroe hopes her husband will be home for the next milestone – their first wedding anniversary on May 9. She added: 'I so hope he's home. We've heard nothing, the lawyer won't answer and neither will the charity Detained in Dubai. 'They are just ignoring us. I'm not doing very well at all, I'm just hoping something will happen next Sunday. But if it's another extension I just don't know how the guys will cope.' Hobby: Mr Clitheroe posted this picture from the Sheraton Deira Hotel in Dubai on February 19 saying he was 'plane spotting in the dark' A Foreign and Commonwealth Office spokesman said: 'We can confirm that three British nationals were detained in Fujairah, UAE on 21 February. They have subsequently been transferred to Abu Dhabi, UAE. 'We are providing consular assistance to the individuals and their families.' Mrs Clitheroe says the three friends were driving past Fujairah Airport, spotting planes and taking notes when they were arrested. Her husband has insisted throughout that they did not take any photographs – heeding warnings on planespotter forums. A crowd-funding site has raised more than £4,300.
