The second victim, a 33-year-old woman, said her $117,000 (£93,980) Graff diamond bracelet was taken from her 59th-floor apartment after she went away on holiday on 3 September.

She reported the theft on 11 September.

A police spokesman told The New York Times a suspect has not yet been identified and investigations were ongoing.

Reports of the thefts came as Mr Trump was expected to return to the Fifth Avenue skyscraper, where he has a penthouse triplex.

The tower is also home to several of the Trump Organisation’s offices.

Mr Trump is due to go to attend the United Nations General Assembly where world leaders will be discussing climate change, Iran and trade wars across five days of meetings this week.

As a result of the president’s impending arrival, security has been on high-alert since before the thefts were reported.

Police have closed a number of streets in the vicinity, including sections of 55th and 56th Streets.
