Egyptian security forces arrested a senior Muslim Brotherhood figure in Sinai on Thursday night, reported Reuters website Aswat Masriya.
Brotherhood Guidance Bureau member Ezzat Abdel-Hamid Gharib was arrested in the North Sinai city of Sheikh Zuweid – the site of numerous armed attacks against security forces since the ouster of Islamist president Mohamed Morsi in July – and flown to Cairo for investigation.
Security forces have been combing local areas since Wednesday when a bus carrying off-duty soldiers was hit by a bomb-laden car. Eleven soldiers were killed and another 37 injured in the incident near Rafah city, also in North Sinai.
Twenty-nine suspects have been rounded up by authorities and are currently being investigated for links to the attack.
Most high profile Brotherhood members have been arrested since Morsi was removed by the army after mass protests against him, including Supreme Guide Mohamed Badie and his deputy Khairat El-Shater. Most now face charges related to incitement to violence.
