Authorities have captured the man responsible for killing one Egyptian Christian and injuring five others on a northbound train in Upper Egypt, security sources said on Tuesday evening.
An unidentified gunman entered the train while it was stationed at the southern city of Samalout in the Minya governorate, some 260 km south of Cairo.
Security sources said the assailant had checked passengers for the green cross traditionally tatooed on the wrists of Coptic Christians in Egypt. After identifying several Copts, the culprit killed one of them and injured five others.
The same sources said that investigators are currently looking into the possibility that the assailant was a policeman, but this remains unconfirmed until present.
