The prosecutor, Joan Illuzzi, spoke at a pre-trial hearing for Mr Weinstein, who is free on $1m (£760,000) bail.
Harvey Weinstein violated his bail conditions by mishandling his electronic ankle-monitor, which left his whereabouts unrecorded for hours at a time, a New York prosecutor has alleged.
A judge deferred any decision about whether Mr Weinstein would face any penalty over the alleged violations until next week.
He is accused of leaving at home a piece of the monitoring technology that keeps the ankle bracelet activated.
