Delhi Police on Tuesday arrested three Babbar Khalsa militants in connection with the twin cinema hall blasts in the capital in May and recovered 2.5 kg of RDX and 10 detonators.

Bishan Lal, Joginder and Ajit Raj were arrested in Jammu on the basis of disclosures of Jaspal Singh, the main accused in the bomb blast, police said on Wednesday.

The trio are believed to be smugglers and suppliers of arms and had allegedly provided explosives and weapons to Jaspal and his associates, police said.

Police said the arrested militants were in direct touch with Satnam Singh, Germany-based mastermind of the blasts.

They had allegedly supplied nine consignments, each comprising 10 kg RDX, one AK rifle and four pistols, since January 2004 for militant activities.

One person was killed and scores injured on May 22 when Babbar Khalsa activists detonated two bombs in Satyam [Get Quote] and Liberty cinema halls in Delhi.
