According to report from Egypt, a French citizen has died in police custody, CEOAFRICA.com gathered.

The man, according to French Embassy in Egypt, was a long-term resident of Egypt, who was arrested for violating an overnight curfew after getting drunk.

Sources said the Frenchman had been arrested on a street in the upmarket Cairo district of Zamalek for violating the curfew. He was presented to state prosecutors, who decided to deport him because he had no valid residency permit, and then put in a holding cell.

The security sources said it was not clear why the man was attacked by his fellow detainees, six of whom were now being held as part of an investigation into his death.

Our source also revealed that one of the prison official said that a post-mortem had found that the man had suffered a "skull fracture" and "internal haemorrhaging".

The curfew has been in place across much of Egypt for more than a month since hundreds of people were killed when security forces cleared two protest camps in Cairo, where people were demanding the reinstatement of ousted President Mohammed Morsi.

Further investigation is underway to reveal the circumstances surrounding his death.
