Una Crown murder: Two men arrested
Two men have been arrested on suspicion of murdering an 86-year-old widow in Cambridgeshire.
The body of Una Crown was found stabbed and burned at her Magazine Lane home in Wisbech on 13 January 2013.
Cambridgeshire Police said a 40-year-old man from March and a 36-year-old man from Wisbech were being questioned.
They are being held at Thorpe Wood Police Station. The arrests come after officers carried out several searches of houses in March and Wisbech.
Mrs Crown's burned body was discovered in the hallway of her bungalow by her niece's husband, John Payne, when he went to collect her for a day out.
Later that afternoon, Mr Payne and his wife Judy were told by police the death was accidental and they could return to the house to sort through her belongings.
A murder investigation began three days later after a post-mortem examination found Mrs Crown had been repeatedly stabbed.
Police believe her body had been set alight in an attempt to cover up the killing.
In May a new team of detectives was brought in to investigate the case.
Officers said a renewed appeal had led to several people coming forward with information.
A £10,000 Crimestoppers reward has been offered for information which leads to the arrest and conviction of those responsible for the murder.
