A British woman believed to be attacked by stray dogs while holidaying in Greece has died.

Retired academic Celia Hollingworth had visited an archaeological site at Mesimvria in northern Greece and was walking part of the way back to her accommodation in Maroneia.

Last spotted at Petrota beach at 4.30 pm on Thursday, she had telephoned her family in London for help after the attack. Her relatives immediately contacted authorities in the area, resulting in a widespread search.

Her body was found by police and firefighters two days later at 10.45 am local time on Saturday, with wounds consistent with being mauled by animals.

According to locals, while the path Ms Hollingworth had taken was commonly in use, it passed near farms guarded by dogs, a source proposing that it is possible she was attacked by a territorial guard dog.

From Wiltshire, Ms Hollingworth worked at Bristol University and was also an Oxford University professor.

An active human rights campaigner, she had helped raise money for charities in Greece helping Syrian refugees.
