The High Election Committee (HEC) detected some violations as polls opened for run-offs in the second stage of Egypt's parliamentary elections on Tuesday.
Ninety-four polling stations opened late across the country out of a total of 12,496 stations.
A number of other infractions were detected including the violation of the electoral silence which was imposed on Monday and prevents candidates from promoting their programmes, HEC spokesman Omar Marawan told MENA.
Other violations include a woman using a national identification card that does not belong to her to vote, and a man who was paying off voters to cast their ballots for specific candidate.
All violators were referred to prosecution and all necessary legal procedures will be taken against them, Marwan added.
