Kerala Chief Minister Pinarayi Vijayan on Tuesday shot off a letter to Prime Minister Narendra Modi over the arrest of former Delhi Deputy Chief Minister Manish Sisodia urging him to dispel the perception that the AAP leader was being targeted for political reasons.

The CBI had arrested Sisodia on February 26 in connection with alleged corruption in the formulation and implementation of the now-scrapped Delhi excise policy for 2021-22.
