The police have evidence that the person responsible is an employee of Janesons. It is also known that: Janesons has rearranged its management structure and will be making 20 senior employees redundant in January. Ben Laidet was made redundant on 8 December for incompetent behaviour. Janesons closest rival, Bertsons, has been suffering from severe financial losses since Janesons installed new technology in the bottling process, which increased their output.
