Yes, in certain circumstances Egypt can prosecute individuals for crimes committed abroad. Article 4 of the Penal Code extends Egyptian jurisdiction to persons who commit acts abroad that make them a perpetrator or accomplice in crimes that affect Egyptian interests or Egyptian nationals. Article 5 further specifies that any Egyptian citizen who commits an act considered a felony or misdemeanor under Egyptian law abroad may be prosecuted upon returning to Egypt.
Importantly, Article 6 provides some procedural protection: a public prosecution (not a private party) must bring such cases, and prosecution cannot proceed if the person can prove they were already tried and acquitted for the same act in the country where it occurred — a principle similar to double jeopardy protections.
As an expat (non-Egyptian national), your exposure under this provision is more limited than for Egyptian citizens, but it is not zero — particularly if the alleged offense involved Egyptian victims or Egyptian state interests. If you have concerns about past conduct in another country, it is advisable to seek confidential legal advice from an Egyptian criminal law attorney before your situation becomes a formal legal matter.
