(ANSA) – Milan, April 30 – Milan prosecutors are taking measures to seize a yacht currently located in Tunisia purchased by the son of Northern League party founder and former leader Umberto Bossi, as part of a wider investigation into the alleged misuse of public funds which earlier this month saw the former treasurer of the separatist political group arrested. Italian authorities have contacted their Tunisian counterparts through a letter rogatory requesting they be permitted to gain control of the vessel that is currently moored in a local port. Former Northern League treasurer Francesco Belsito was arrested in April on charges of alleged criminal association and aggravated fraud. He had been under investigation since a probe into alleged misuse of public funding to the party broke last year in a scandal that led Bossi to quit. Earlier this month, reports emerged of a 2.5-million-euro yacht that was bought by Riccardo, one of Bossi's sons, as part of an alleged widespread embezzlement scheme that involved public funds.
