Jerusalem Post blogger Ahmed Meligy was reportedly arrested in Egypt on Monday.
An associate of Meligy, whose blog "Egypt's Missing Peace" has been critical of the Egyptian government, informed the Post that he had been arrested in Alexandria.
No other information was immediately available, and the Post was unable to confirm Meligy's whereabouts.
Meligy had recently informed Post Blog editor Lidar Grave that he would have to take a short hiatus from blogging because he was receiving threats.
In early November, Meligy opened a blog post critical of Egyptian President Mohamed Morsi with the words, "I hope that I don’t get arrested for this one." He went on to say "the Muslim Brotherhood is creating a dictatorship that will set back my Egypt for years to come."
