A youth soccer coach who authorities say threatened a father who wanted more playing time for his 6-year-old son was arraigned on harassment charges Saturday and ordered to stay away from the other parent.

Judge Robert Pipia in First District Court, Hempstead, released Robert Riccuiti, 45, of Glen Head, on his own recognizance but ordered him to stay away from the alleged victim, unless there is "incidental contact" at the school their children attend.

Nassau police said they arrested Riccuiti after he sent an email to the man on May 16 that contained foul language and "a verbal threat of physical violence with a baseball bat."

In court Saturday, prosecutors said Riccuiti had admitted to sending two emails that were characterized as vulgar and threatening. Riccuiti declined to comment after his release.

The father he allegedly threatened had questioned his son's lack of playing time and the philosophy of the soccer program, police said.

The public defender said in court that Riccuiti has been principal for 11 years at the public Vive School in Yonkers, which provides education and support services for older teens and adults. She also said he is pursuing a doctorate at Fordham University.

According to news reports, a Yonkers principal with the same name was briefly hospitalized in 2010 after being assaulted by a student.

A message left at Riccuiti's home Saturday morning was not immediately returned, and calls to Yonkers schools officials were not answered. The parent he allegedly threatened could not be reached.

Riccuiti was represented Saturday by a Legal Aid Society attorney. That group's offices were closed Saturday afternoon. His next court date is scheduled for June 23.
