Parameswaran was transferred to Singanallur open jail here, official sources said.
The decision comes after 38 inmates of the school (formerly Sub-Jail) observed a fast today, alleging that Parameswaran was demanding money from their relatives to show official favours.
Earlier in the day, advocates of Pollachi Bar Association also staged a demonstration against the official for reportedly demanding money to grant bails for inmates.
Parameswaran was not immediately available for his comments.
