One person has reportedly been killed after police in Chad cracked down on protesters who were demonstrating over the alleged gang rape of a young girl.

Hundreds of protestors took to the streets in the capital N’Djamena on Monday angry after images of the victim were posted on social media.

One protester was reported to have been shot dead as police moved to disperse the demonstration with tear gas.

However, police spokesman Colonel Paul Manga denied that any protesters had been killed and said two of the girl’s alleged rapists had been arrested.

Protesters said the girl, named as Zouhoura, was kidnapped last weekend and gang-raped by five young men from the families of senior officers.

The men then allegedly posted a video online showing the victim in tears. The video has since been removed.

On Monday morning, pupils from Zouhoura’s high school and other protesters gathered outside her home and marched to the court to demand compensation for the girl.

Singing the national anthem, they marched holding banners that read “Justice for Zouhoura” and “We are all Zouhoura, our dignity is being denied”.

“As we arrived not far from the court, police fired tear gas. They also used live bullets,” one protester told AFP.

“Then they chased us through the city, and at the Liberty High School one of us fell, hit by a bullet.”

Manga said the situation was “under control”, adding: “There were no victims, to my knowledge.”

In a statement, Chad’s president Idriss Deby Itno condemned the rape as a “barbaric, vile and unmentionable act” and swore “justice will be done.”
