A mayor of a city on Tenerife has written to the Spanish ambassador to the UK raising concern about Seth Martin who has been missing from his home in York for over 10 days.

North Yorkshire Police today (Wednesday, March 6) said officers continue to search for the 31-year-old last seen at about 9am at his home address in the Clifton area on Saturday, February 24.

The search for the Spanish national is focused on the River Ouse after a report of a man in the water near Clifton Ings at 4.30pm on Saturday, February 24, a force spokesperson said.

José Manuel Bermúdez, mayor of Santa Cruz on Tenerife where Mr Martin is originally from, wrote to the Spanish ambassador to the UK, José Pascual Marco Jiménez.

In his letter the mayor asks the ambassador to take interest in the case and urges him to act “as soon as possible, since each day that passes is crucial” in the search for Mr Martin.  

A North Yorkshire Police spokesperson said officers have been carrying out a “number of enquiries including reviewing CCTV footage but the ongoing search is now focused predominantly on the river”.

The force is keeping in touch Mr Martin’s family while enquiries continue, the spokesperson added.

Family of missing man 'distraught and desperate after a week of uncertainty'

In a statement released to The Press on Saturday (March 2) Mr Martin’s family said they were “distraught and desperate after a week of uncertainty since his disappearance”.

“Despite local efforts, Spanish authority and institutions have not yet participated in the investigation or provided assistance,” they added.
