Khaled Said died on June 6. Witnesses said the two policemen dragged Said out of an Internet cafe and beat him to death.

But two state autopsies insisted Said died of suffocation after swallowing a packet of drugs.

The autopsy results were met with derision and international calls for a transparent investigation after photos of Said's body were circulated, showing his mangled face.

Prosecutor Abdel-Meguid Mahmoud on Saturday asked an Alexandria criminal court to set a trial date. Lawyers say the charges carry a maximum sentence of 15 years.
