Ahmad Attoun had taken shelter in the ICRC building along with another Hamas legislator and a former Hamas government minister after Israeli authorities revoked their Jerusalem residency permits.
Israel captured East Jerusalem in a 1967 war and regards all of Jerusalem as its capital, a claim that is not recognised internationally.
Along with the United States and the European Union, it considers the Islamist Hamas movement a terrorist group, and acted to expel the men for being members of it.
The police spokesman and a security guard at the ICRC building said paramilitary police disguised as Palestinians had grabbed Attoun at the entrance to the offices and arrested him.
He was taken into custody a day after Palestinian President Mahmoud Abbas mentioned the men`s case in a speech on his return to the occupied West Bank from the United Nations, where he applied for recognition of full Palestinian statehood.
The other two Hamas men remained inside the ICRC building.
In the speech, Abbas accused Israel of "ethnic cleansing" that included "decisions to expel elected representatives" from Jerusalem.
In a statement issued in June 2010, after Israel ordered them to leave Jerusalem, the three Hamas men wrote: "We as sons of Jerusalem have never left it before ... we emphasise that we will remain here and never leave it."
Hamas, locked in a bitter rivalry with Abbas`s Fatah movement, won a Palestinian legislative election in 2006. Hamas seized the Gaza Strip in 2007 after a unity government with Fatah collapsed into bloodshed.
The ICRC has said it told Israeli authorities that international humanitarian law prohibited the forcible transfer of Palestinian residents from their homes, for whatever reason.
The organisation also said it had informed the three Hamas members that ICRC premises had no special status and the ICRC could not prevent police entering the building to arrest them. (*)
