Twycross Zoo elephant abuse allegations: No action to be taken
Two former members of staff at Twycross Zoo will not be prosecuted over allegations of mistreatment of animals.
Three members of staff at the Leicestershire attraction were dismissed and arrested in September.
Last week the police handed over files on two of these to the CPS. No further action was taken over the third person.
But now officials have said there is "insufficient evidence for a realistic prospect of conviction".
The staff were arrested after the zoo reported concerns that two elephants had been mistreated.
A CPS spokesman said: "[The files] been examined in detail and we have informed Leicestershire Police that there is insufficient evidence for a realistic prospect of conviction, in that the conduct shown is not sufficient to prove a criminal offence under the Animal Welfare Act 2006."
The elephants suffered no lasting ill effects.
The zoo had previously condemned the incident as the actions of "rogue individuals".
