It comes a day after Chief Minister Mamata Banerjee too indirectly accused the central agency sleuths of 'planting evidence'. 'I received a message yesterday from someone who said that Abhishek will soon be arrested as all evidence from his computer had been retrieved. Yes they have retrieved some files from the computer and planted their own files there. But we are not fools. We have also extracted all the evidence of planting files which were not there in the computer. A general diary has also been filed in the matter,' the Chief Minister said on Monday, while addressing a gathering on the occasion of the foundation of Trinamool Chhatra Parishad, the students' wing of the party. Meanwhile, the ED has claimed that they have already appraised the city police commission about the files downloaded by one of his officers inadvertently while searching for a students' hostel for his daughter who has recently got admitted to one of the reputed engineering universities in the state. The central agency has also clarified that the inadvertent file downloading relating to the students' hostel was done after the raid and search operations were concluded and they were done under CCTV monitoring and in presence of the employees of the company as well as the independent witnesses present at the spot then. The two independent witnesses present at the spot included a deputy manager and an assistant manager of state-run Punjab National Bank.
