A federal judge in Minnesota has blocked the release of a former state senator accused of soliciting a teenage girl for sex after he allegedly obstructed the investigation by attempting to hide evidence.

A judge on Monday blocked the release of a former Minnesota state senator charged with soliciting a minor, after prosecutors leveled fresh allegations that he tried to obstruct the FBI's investigation from jail.

Federal authorities want former state Sen. Justin Eichorn to remain in custody ahead of his trial for allegedly seeking sex with a 17-year-old girl, claiming the ex-Minnesota lawmaker lied about having access to a gun and arranged to cover up evidence that could be used against him in court.

Former Minnesota State Senator Justin Eichorn (R- Grand Rapids) will remain in custody, at least for now. A federal judge has blocked his release after he allegedly obstructed the investigation into accusations that he solicited a teenage girl.

Republican Justin Eichorn of Grand Rapids resigned from the Minnesota Senate last week after being charged with attempted coercion or enticement of a minor.
