Detectives investigating the killing of Mrs Crown arrested a 40-year-old man in March and a 36-year-old man in Wisbech in June.

Both were taken to Thorpe Wood Police Station while officers carried out searches at several addresses in March and Wisbech.

Neither will face any further action, Cambridgeshire police revealed today.

The arrests came a month after the murder investigation was re-launched with a fresh team of detectives from the Bedfordshire, Cambridgeshire and Hertfordshire Major Crime Unit. The renewed appeal led to several people coming forward with information.

Mrs Crown was last seen alive on Friday, January 11, last year, at her Wisbech home but had spoken to a friend by telephone at about 5pm on the Saturday.

Her body was discovered by a family member at her home in Magazine Lane the following morning.

She had been repeatedly stabbed then set on fire in an apparent attempt to disguise her injuries and destroy evidence.

Detective Chief Inspector Sharn Basra said: “We have really been encouraged by the response from the public so far.

“We believe there are people out there with information who we haven’t spoken to and I would urge them to call police.”

A £10,000 Crimestoppers reward is on offer for information which leads to the arrest and conviction of those responsible for the murder.

Anyone with any information should call police on 01707355666 or Crimestoppers on 0800 555111.
