“The foreign ministry continues to follow up on the progress in the investigation in order to preserve the citizen’s rights and ensure the speedy return of his remains,” the ministry said in a statement.

Italian police arrested last week three men, including two brothers and their sister’s partner, on suspicion of murdering the 44-year-old Egyptian in Pavia province in northern Italy last month.

A search is underway for more suspects in the crime, the ministry added.

Mansour’s charred remains were found inside a burnt car in a wooded area in Cilavegna commune, where he resided. His body also had gunshot wounds.

The investigation revealed that a personal dispute between the victim and the family of his daughter’s Italian mother was the cause of the crime, the Egyptian ministry confirmed in today’s statement.

The perpetrators ambushed Mansour and killed him in an industrial building with at least three shots before setting his body ablaze inside his car, Italian media quoted local authorities as saying on Tuesday.

The Egyptian foreign ministry said earlier this month that it is communicating with Italian authorities to follow up on the investigation into Mansour’s murder and that it is working on repatriating his body to Cairo.
