New allegations against former state Senator Ernie Newton have surfaced just days before he is set to be sentenced on bribery charges.

In court documents filed Thursday, federal prosecutors claim Newton worked with a reputed mobster and his associate to stop police raids on businesses and advance their business interests. In addition, prosecutors say in return for the favors, the reputed mobster and his associate helped Newton bail his son out of prison. Prosecutors say they also gave Newton campaign contributions, which he used pay bills and personal loans.

Newton resigned last year after pleading guilty to accepting a $5,000 bribe, diverting campaign contributions and evading federal income taxes. Newton will be sentenced on the bribery charges Tuesday. Prosecutors are seeking a five to seven year prison term.
