Egypt's interior ministry released on Tuesday a video showing CCTV footage of the EgyptAir hijacker going through security checks at Alexandria's Borg El-Arab Airport ahead of boarding flight 181, said a ministry statement.
Newly appointed aviation minister Sherif Fathy said earlier in the day that airports are expected to witness tighter security measures.
Hijacker Seif El-din Mustafa, who diverted on Tuesday EgyptAir flight 181 – en route from Alexandria to Cairo – to Larnaca, Cyprus surrendered to Cypriot authorities after holding hostages for more than seven hours, though his exact motives remain unclear.
Egyptian officials said the hijacker demanded the plane land in Turkey, but its fuel could take it no further than Cyprus.
Mustafa, who will be soon deported to Cairo, is currently being detained in Larnaca.
EgyptAir has sent a plane to bring the passengers from flight 181 back to Egypt.
