The Karnataka police on Sunday claimed they solved the last year's mysterious Hubli bomb blast case with the arrest of a man and his aides who allegedly involved in several criminal activities.

Inspector General of Police Ragavendra Auradhkar said Nagraj Jambagi and his aides were involved in the blast case which occurred in the court premises during the last Assembly polls. No person was injured as the courts were shut due to a holiday.

The IGP also said that this was the same team which had planted a bomb on the Belgaum-Hubli highway last year.

However, this bomb failed to explode as it was raining heavily. After high drama, the bomb squad finally retrieved the bomb.

The IGP said investigations showed that they carried out the blasts to bump off their rivals and also causing harm to the police force.

Explaining the operation, the IGP said that the police nabbed Nagraj and eight others in connection with various criminal cases that had occurred at Bagalkot, Karnataka. The police also seized Rs 11,08,250 from them apart from silver, gold and two motor cycles.

The IGP said that Nagraj led the gang which was involved in seven murder cases in North Karnataka. Besides, the gang was also allegedly involved in several cases of abduction.
