As the investigation by Egyptian police into the bombing of a Coptic Church in Alexandria goes on, there have been a number of reported arrests.
Among those held are a group of conservative Islamic followers known as Salafists.
Scores have been reportedly arrested by police over recent days - one of them, 31-year-old Sayyed Bilal, is now dead.
His family says Bilal died as a result of torture, and they have filed an official complaint with the prosecutor's office.
