A Kolkata court on Monday issued a non-bailable arrest warrant against Ashok Todi, the father-in-law of Rizwanur Rehman, who was found dead last year a month after his marriage to the industrialist's daughter, and two of his relatives.

Seventh metropolitan magistrate Bhivas Chatterjee of the metropolitan court issued the warrants saying their non-appearance despite summons was nothing but an attempt to drag on the proceedings.

The warrants were issued against Ashok Todi, his brother Pradip Todi and brother-in-law Anil Saraogi who did not appear before the court on Monday despite summons being issued against them.

The court sent another accused Moinuddin alias Pappu to judicial custody.

The court, however, extended the interim bail of IPS officer Ajay Kumar and two other officers of Kolkata Police, accused of threatening Rizwanur at the police headquarters after his marriage with Priyanka, Todi's daughter, while directing them to appear before it on November 3.

The judge rejected the bail prayer of Pappu, who surrendered before the court earlier in the day, and sent him to judicial custody till November 10.

The CBI in its chargesheet had alleged that Pappu had taken Rs 11 lakhs from the Todis to ensure that Priyanka, went back to her parents from the house of Rizwanur who was from a modest background.

All the seven accused were charged with abetment to suicide, criminal intimidation and conspiracy.

The CBI is investigating the case as per a direction of the Calcutta High Court on a plea by Rizwanur's mother Kishwar Jahan who had claimed that she did not have faith in the local police.
