In Goa, police have made the first arrest in connection with the Margao blasts when a man with alleged links to a Hindu right-wing group 'Sanatan Sanstha' was picked up yesterday. The arrest was effected as Maharashtra's Anti-Terrorism Squad sleuths joined the state police in investigations but no details or the identity of the person was given. The searches were conducted at the Sanstha office in Nesai near Margao town, 30 km from Panaji. According to the police, the outfit with suspected links to 2008 Malegaon blast accused Sadhvi Pragya Singh Thakur is allegedly involved in the blast. In an attempt to crack the case quickly, the state government formed a Special Investigating Team (SIT) to probe the blast in which the two dead were activists of the Sanstha. Deputy IGP Ravindra Yadav told reporters in Margao town that one arrest has been made in the blast on Diwali eve on Friday night and that the arrested man belongs to Sanatan Sanstha outfit.Police earlier had detained five members of the outfit which has recently come under the scanner of security agencies. The two victims– Malgonda Patil and Yogesh Naik'were booked under various offences including waging a war against the state. The Sanstha has denied the allegations of its involvement in the blast terming them as "baseless". <br/> <br/>
