Prosecutors in Egypt have ordered the detention of 13 teenage boys arrested on suspicion of harassing two female foreign tourists at the Giza pyramids.
Egyptians expressed outrage on social media last week after a video showed a group of youths haranguing the young women at the archaeological site.
A prosecution statement said the boys were between 13 and 15 years old.
They have claimed that they only wanted to take photos with the tourists and had not intended to cause any distress.
The boys would be held at a juvenile detention centre until the investigation had been completed, the prosecution statement said.
It added that a complaint accusing the boys of verbal and physical harassment had been filed by a tourist guide who filmed the video, rather than the women themselves.
In the 35-second clip, the guide can be heard complaining that Egyptian boys are "running after the foreigners" and saying that he wants the tourism minister to be aware.
The boys are seen holding up mobile phones as they crowd around the women, who attempt to get away. One of the women tries to push a boy away after another appears to touch her from behind.
