The Special Investigation Team probing the 'Ice Cream Parlour' sex case,today questioned another former Kerala High Court judge in connection with certain allegations against him regarding the case. A police team led by Thrissur Commissioner,P Vijayan,which arrived at the residence of Justice K Narayana Kurup,who was also former acting Chief Justice of Madras High court,this afternoon,began questioning him. Yesterday,the SIT had questioned Justice Thankappan at his residence at nearby Chottanikara. The SIT,led by ADGP Vinson M Paul,had earlier sent notices to the two judges to appear before it for interrogation following allegations by K A Rauf,a close relative of IUML General Secretary,P K Kunhalikutty,who is allegedly embroiled in the case. Rauf had alleged that the two former judges had delivered judgements favouring Kunhalikutty. Justice Kurup had sought three weeks time to file a detailed reply before SIT. Justice Thankappan had later in the night denied that he was 'questioned' and said the officers had come to "collect some information" in the case and he had told them what he knew. He had maintained that police cannot question him without taking the court's permission even though he was a retired high court judge. The case relates to allegations that surfaced in late 1990s that an ice cream parlour in Kozhikode city was being used as a cover to lure young women into prostitution. Kunhalikutty quit as Industries Minister in the Congress-led UDF Government in 2004 in the wake of the allegations. He,however,did not figure as an accused in the case.
