"Palestinian Authority's security services detained Sunday Abdelqaher Serour, office manager of the jailed speaker of Palestinian Legislative Council (PLC), Aziz Dwaik, who has been imprisoned by Israel since last summer.
The PA's security forces have been reportedly arresting scores of Hamas-linked people in the West Bank, since the Islamist group has seized the Gaza Strip in mid June.
The PA's Fatah-loyal forces have recently also sealed off almost 90 Hamas-run charities, on grounds of 'fraud and unaccountability'. Hamas denied the accusations, saying the move intended at undermining its West Bank-based structure.
Hamas sources claimed that Serur, has been summoned by the preventive security service's headquarter for interrogation, and then he has been detained.
Acting speaker of parliament in Gaza, Ahmad Bahar, held the preventive security for the detainee's safety, because of what Bahar says, the detainee's heart condition.
President Mahmoud Abbas of Fatah outlawed Hamas in June, in the wake of what Abbas termed a ' coup against legitimacy' and formed a caretaker government in the West Bank.
Hamas' takeover of the coastal region came amidst a power struggle with Fatah, following Hamas's landslide victory during last January's PLC's elections."
