Please help us locate our dad!

Desperately seeking any information on the whereabouts of Michael William Leek aged 78 years (known as Mick or Micky) who lives in Puerto Rico. He was taken from the sunspot bar by ambulance last Thursday evening with no ID or telephone on his person. His family in the UK have contacted all of the hospitals but can't locate him, we have involved the British Consulate in Gran Canaria and they can't find him either so he has now been reported as a missing person. We are beside ourselves with worry and just need to know where he is. He has infected ulcers on his feet and legs so has no mobility and his speech is very unclear. Please, please help us!
