Italian prosecutors have placed five members of the Egyptian security forces under investigation for their alleged involvement in the case of the murdered Italian student, Giulio Regeni. The suspects include a general and other senior figures.

It's understood they're to be investigated in connection with Mr Regeni's kidnapping.

Nobody has yet been accused of killing the student - who was researching the politically sensitive issue of trade union activity in Egypt.

His mutilated body was found by a road on the outskirts of Cairo. The Egyptian authorities have repeatedly denied any involvement in the murder nearly three years ago.
