A major search operation is under way for a woman who went for a walk on the Solway estuary but phoned to say she was stuck in the mud.

Shona Campbell, 74, was staying at the Moss-Side caravan park in Cummertrees but has not been seen since the alarm was raised at about 17:00 on Monday.

It is understood she made the call to report getting into difficulties herself.

Police said “extensive searches” were being carried out involving specialist resources and they were working with other emergency services.

Ms Campbell is believed to have been wearing jeans, a brown wax jacket and wellington boots.

Insp Amy Ritchie said: “Every effort is being made to find Shona and her family are being supported by officers at this difficult time.

“From our inquiries so far, we know Shona left the caravan park to go for a walk before getting into difficulty and has not returned.

“Local officers and search advisers are being assisted by specialist resources.”

She appealed to anyone with information “no matter how small” to get in touch.
