Thiruvananthapuram, Sep 1 (TIWN) With the Kerala Police on Tuesday formally arresting four Congress workers and taking into custody another four alleged to be part of the conspiracy to eliminate two activists of the CPI-M's youth wing, a war of words has broken out between the two parties. The Congress is demanding a CBI probe into the double murder.

The four were arrested on Monday and another four accused were being questioned on Tuesday.

The murders took place close to midnight on Sunday, when 24-year-old Haq Mohammed and 32-year-old Mithilaj, both youth wing activists of the CPI-M, were hacked to death by five people who came on bikes armed with swords and knives at Venjaramoodu, about 25 kms from the state capital’s suburbs.

According to the police, the arrested include Shejith, Ajith, Najeeb and Sathi, while two others — the prime accused Sajeev and Sanal — are yet to be arrested. Four more people have been picked up for questioning.

State Industries Minister E. P. Jayarajan, soon after visiting the homes of the victims alleged that the Congress MP from the locality Adoor Prakash knew everything about the incident.
