It is also learnt that the teams of National Investigation Agency and National Security Guards have been sent to Ludhiana to collect evidences while the blast incident is being investigated by the Punjab police.

According to the preliminary report, the blast took place around 12.25 p.m. on the third floor of the court premises. The Court advocates are on strike, therefore less number of advocates were present when the blast took place.

Recently, Punjab has witnessed incidents of sacrilege in Gurudwaras and the Ministry of the Home Affairs issued an advisory to the state government to take adequate measures to prevent these incidents just before the state assembly election due in next year.
