A man has been arrested on suspicion of the murder of an 86-year-old retired postmistress, who was found dead in her bungalow 11 years ago.

Una Crown was found in a pool of blood and with her clothing burnt in her hallway in Wisbech, Cambridgeshire.

Her death in 2013 was initially treated as an accident when she was found by emergency workers on 13 January, after family and neighbours became concerned for her welfare.

A murder investigation was launched four days later.

Cambridgeshire Police said a 69-year-old man from Wisbech had been arrested on suspicion of the murder of Ms Crown.

The force said the suspect, who was arrested on Monday morning, remains in custody at Thorpe Wood Police Station in Peterborough.
