Paterson Mayor Joey Torres surrendered to authorities and he refused to answer any questions while walking into police headquarters.
A state grand jury indicted Torres and three of the city's public works supervisors on official misconduct charges last week.
The indictment alleges Torres instructed the public works department employees to do work at a liquor warehouse leased by the mayor's daughter and nephew while being paid overtime by the city.
The three workers have all been criminal processed while Torres, who maintains his innocence, has gone about his normal schedule as mayor since his indictment.
Torres, a Democrat, was elected in 2014. He also served two terms as Mayor of Paterson between 2002 to 2010. And although Torres used to be well liked by the public, these indictment charges are making Paterson residents weary of his regime.
No word yet as to when Torres' arraignment will be.
