A woman has been given a suspended prison sentence and 200 hours community service for sparking an anthrax scare at a Kent nursery.
The court was told Pratt sent the letter following a family feud
June Pratt, 50, of St Paul's Road, Margate, was convicted of sending a letter containing a threatening message at Margate Magistrates Court.
The court heard Pratt sent a white powder labelled anthrax to the Elms Nursery, run by her sister, on 6 March.
Pratt sent the substance, which was cornstarch, following a family feud.
Magistrates were told the white powder and a note saying, "Anthrax - start taking antibiotics", were discovered when Pratt's sister, Sandra Berwick, opened the hand delivered letter.
The court heard the emergency services were called, 34 children were segregated and nine members of staff were put into solitary confinement.
Mrs Berwick and the nursery deputy were quarantined and the road was cordoned off.
Police traced Pratt through DNA left on the stamp and through hand writing on a letter of complaint she sent the same day to OFSTED.
Det Sgt Tristan Kluibenschadl said: "This offence was one that was carried out due to sheer jealousy and rage at her sister's success.
"It was an evil crime that was carried out without through for the welfare of the many innocent children or staff at the nursery.
"It was also an offence that wasted thousands of pounds of public money by engaging the time and resources of all three of the emergency services that were involved."
Pratt was given a four-month prison sentence, suspended for two years, a 12-month supervision order, 200-hours community service and ordered to pay £60 costs.
