Authorities have beefed up Election Day security for Donald Trump by parking dump trucks filled with sand outside his Trump Tower building on Fifth Avenue.

Police said Tuesday that similar precautionary measures were being taken at other sites around midtown Manhattan where Trump and Hillary Clinton plan to spend election night.

Authorities say the heavy trucks could block an attempted car bombing. They say there are no confirmed terror threats.

The NYPD had previously said it will deploy more than 5,000 police officers to keep order on election night. The deployment also includes police helicopters, mobile radiation detectors and bomb-sniffing dogs.
