The public prosecutor began presenting its demands to the court after the defence lawyers had had their say.

The initial interrogations of the biker gang took three days at the Lisbon Criminal Investigation Court.

The gang members are accused of criminal association, attempted murder, theft, GBH and drug trafficking.

The investigation has been going on for some time but the arrests came shortly before a major motorcycle meeting in the Algarve where police were concerned there could be major violent incidents between two groups of bikers.
