Three suspects have been detained in connection with the Margao blast from Baramati district of Maharashtra and brought to Goa, police said on Sunday.
They were detained from Baramati rural police station jurisdiction and handed over the Goa police team on Saturday night, they said.
Baramati police sources confirmed that they were detained and not arrested by Goa police.
Two persons were killed on the blast on Diwali eve.
Two Sanatan Sanstha seekers were arrested by Goa police on Saturday for hatching a conspiracy to create panic in the state.
Superintendent of Police and spokesperson for Goa Police Atmaram Deshpande, when contacted in Panaji, stated that there have been no arrests besides the two on Saturday.
However, he refused to comment on the detention of the three at Baramati.
Sources in the department, however, confirmed that the mobile SIM cards used by some suspects in the Margao blasts were registered in the name of two persons detained in Baramati.
