Thiruvananthapuram, Sep 8 (IANS): Kerala Industries and Sports Minister E.P. Jayarajan on Thursday said the Union Government should behave in a responsible manner and "should not stoop low", after the Centre sought a report on a crude bomb attack on a BJP office here.

His response came following reports that Union Home Minister Rajnath Singh called up Chief Minister Pinarayi Vijayan following the crude bomb attack on a BJP state unit office here on Tuesday night.

While the state and national leaders of the Bharatiya Janata Party (BJP) alleged that it was the work of the CPI-M, the ruling party in the state has denied it.

Following the attack, Singh called up Vijayan and expressed concern over the incident and sought a report about it from the Home Secretary.

"All I wish to say is that the Centre should not stoop low and should not be in a hurry because when the truth comes out tomorrow they might have to apologise," said Jayarajan.

State BJP president Kummanem Rajashekeran, who was in the office an hour before the crude bomb attack by a person on a two wheeler, told reporters on Thursday that he has "lost faith in the police". He said if the CPI-M-led government is "serious they can nab the culprits in a short time, but they won't do it".

Meanwhile the national leadership of BJP has decided to send a delegation of party MPs to the state in the wake of the attack.
