Lawyer Paul Knowsley said Otto had suffered "a spectacular fall from grace."
He had since taken steps to address the cause of his offending and written letters of apology to the complainant and the court.
"Pulling himself up by the bootstraps," he had found new work and was determined to pay back the rest of the stolen money.
Judge Hobbs said the fact that Otto's offending was driven by a gambling addiction was no excuse. He had used the money as if it were his own.
However, he was "clearly remorseful."
The judge sentenced Otto to three months' home detention and 100 hours' community work. He must also undertake a gambling prevention programme and pay the remaining reparation.
