Former Minister Johnston Fernando has filed a Writ petition before the Court of Appeal seeking an order to prevent his arrest.
MP Fernando and several other Sri Lanka Podujana Peramuna (SLPP) followers have been named as suspects in the case filed over the violent attacks on protesters on May 9.
A travel ban has already been imposed by the court against MP Fernando.
However, he argued that the Attorney General naming him as a suspect in the case and the CID arresting him is against the law, hence, filed a Writ petition against his arrest.
The IGP and the Director of the CID have been named as respondents in the petition.
