"In preparation for tomorrow's presidential election, the NYPD has developed a very comprehensive security plan. Well over 5,000 uniformed officers will be assigned to election duty, various times of election duty throughout the day," Gomez said on Monday, broadcast by the ABC News channel.
The operation involves more than double the number of officers than the previous election day operation, he added, urging New York residents to alert police authorities via the terror hotline in case of any suspicious activity.
Other police officials reportedly dismissed threats by the Islamic State (IS), a terrorist organization outlawed in both the United States and Russia, to carry out attacks on US soil.
US presidential elections are taking place on Tuesday and come less than two months after the New York and New Jersey bombings which injured dozens of people. Ahmad Rahami, an immigrant from Afghanistan, has been accused of plotting the attacks.
