A pensioner thought to have travelled to Cornwall by train has now been missing for almost three weeks.

Devon and Cornwall Police have renewed their appeal for help from members of the public today (Monday) as the need to find Alvin Diaz grows ever more urgent as the days go by.

The 72-year-old was reported missing from his home in Brentor, Devon on Wednesday, March 27 and the last believed sighting of him is at Penzance Railway Station on the same day.

He is thought to have travelled by train to Cornwall, with CCTV appearing to capture him getting off at Penzance and walking along the platform.

Alvin is said to know the areas of Penzance, St Buryan, Mousehole and Marazion, as well as the Isles of Scilly, and it is thought he may have gone to one of these – although he could be elsewhere in Cornwall.
