Egypt's Prosecutor General Nabil Sadek has referred four people to criminal court on responsibility for the collision of two trains in the Nile Delta in February that killed seven people and injured 49 others.

In an official statement issued by the prosecutor general's office, four railways workers from the signaling system department in the railway authority were referred to court for violating railways safety bylaws, leading to the collision of a passenger train and a cargo train.

Investigations revealed that the railway authority sustained financial losses in the collision of EGP 439,079 as well losses equal to EGP 66,892 due to obstruction of rail movement for several hours after the accident.  

The prosecutor general also ordered the detention of the four workers pending trial.

The country’s prosecutor-general on Thursday appointed a seven-member committee to inspect the scene of the crash and investigate the technical functioning of the trains, the network's signaling system, and operation equipment.
