LDF members moved into the Well of the House with banners demanding the arrest of P K Basheer, representing Ernad segment in Malappuram District and named as sixth accused in a FIR in connection with a double murder case in Malappuram.
Speaker G Karthikeyan announced the suspension of the Question Hour and other proceedings before the adjournment of the Assembly for the day.
Karthikeyan also expressed displeasure over the LDF protest in the House, saying it was unfortunate that the Opposition was disrupting the proceedings.
The government had stated that it was of the view that a person could not be arrested just because of his/her name figured in the FIR filed by police in a case.
Opposition alleged that the government was protecting the MLA of IUML, second largest partner of ruling UDF.
But the ruling front termed the opposition protest as a 'drama' to divert the attention of public from the "embarrassment and image loss" caused to CPI-M over the killing of Revolutionary Marxist Leader leader T P Chandrasekheran last month in connection with which some of its party activists have been arrested.
