Irish grandfather John Murphy 59 destitute in Dubai

Hi, my name is Julie and I am fundraising for Irish grandfather John Murphy 59 from Limerick, who is destitute and trapped in Dubai, despite being found innocent of the charges that first landed him in prison. John is desperate to get back to the UK and is in urgent need of medical and dental treatment. He is currently living on the streets and is forced to spend his days riding the metro to survive.

Please help so he can get home to see his family.
