TOKYO (AP) — Tokyo Olympic organizers are expected to scrap the logo for the 2020 Games on Tuesday following another allegation its Japanese designer might have used copied materials in presentations of the design.

Up to now, Olympic organizers have supported designer Kenjiro Sano against allegations of plagiarizing the design, but Japan's national broadcaster NHK said that the support will be withdrawn as a result of new accusations that Sano allegedly used an image from someone else's website without authorization.

There was no immediate comment from Olympic officials on reports that the logo will be withdrawn. But organizing committee executives were meeting Tuesday to discuss the issue and an announcement was expected following the meeting.

Prime Minister Shinzo Abe told reporters that the organizing committee was making "an appropriate decision" and that the Olympic must be an event that is celebrated by everyone.

The logo scandal is another embarrassment for Japan, which scrapped the initial design of the main stadium for the Games following public uproar over its skyrocketing cost estimate.

Sano has faced allegations of plagiarism since the logo's July debut. A Belgian designer sued the International Olympic Committee over similarity of his logo for a theater in that country. Sano denied the allegation, but has faced other plagiarism questions over his past designs.

The latest suspicion surfaced late Monday, when he was alleged to have taken a photo from someone else's website and used it in his presentation of the Olympic logo, including one at its debut event.

Sano allegedly altered part of a photo of a Tokyo airport lobby, replacing images of banners hanging from the ceiling with those of his Olympic logo. Details in the two photos, including people on the floor and the size of the banners, were identical in footages shown by NHK.
