DiNizo has been coaching girls basketball in Westchester County for nearly 20 years and investigators are concerned there might be other victims.
58-year-old Richard DiNizo's house is shadowed in darkness.
This is where investigators say in 2010 the long-time basketball coach abused a 10-year-old girl.
It's unclear what evidence prompted state police to investigate three years later, which ultimately lead to DiNizo's arrest.
"The information came to our attention about 48 hours ago. We had investigators working on it pretty much around the clock to identify both the victim and the defendant. We were able to do so fairly quickly and we picked him up this morning," said Major Michael Kupy, New York State Police.
We don't know how DiNizo allegedly abused the young girl.
The 58-year-old is said to have coached girls basketball in Westchester since the mid-1990's, including for the Westchester basketball association.
"I'm totally in shock about it. It's totally unbelievable," said Edward Gaerlan, a neighbor.
Neighbors tell Eyewitness News DiNizo was having marital problems and was recently staying at a friend's house down the block.
News of his arrest surprised Edward Gaerlan who lives next to DiNizo.
"I only have good things to say about him. I mean as far as my exposure to him. He's been a pleasant person, and a good neighbor, and basically a nice guy," Gaerlan said.
DiNizo is charged with one count of a criminal sexual act, which means he faces up to 25 years in prison.
More charges, state and federal, could come.
