Jonathan Robinson was handed over the copy of the charge sheet at the Judicial Magistrate's Court at Valliyoor last evening, police said today.
The additional charge sheet mentioned details about Robinson's potency test, conducted earlier.
Police had registered a case against Robinson in 2011 based on a complaint from a Bengaluru-based NGO that he had allegedly abused a 15-year old boy, an inmate of the home for children in Valliyoor.
