Singh was arrested last year on 18 December in hotel in the Algarve and remains in custody at a prison in Évora.


He was arrested by SEF border and immigration inspectors on an extradition request issued by Interpol.


He is wanted by India for alleged involvement in bomb attacks carried out in 2010 in the Patiala and Ambala regions, as well as being accused of being behind the murder of the leader of the national Hindu movement in 2009.
