Israel rearrested a Palestinian parliamentarian from the Hamas terror group on Monday, the Palestinian Prisoners Club said.
Omar Abdul Razek, a member of the Palestinian Legislative Council, was arrested by Israeli forces in the town of Salfit in the northern West Bank, overnight, the prisoners club said in a statement.
He had only been released in November, it added.
There was no immediate confirmation from Israeli officials, with the Shin Bet security agency denying it had made arrests overnight. The army declined to comment on specific cases.
The Palestinian Legislative Council last held elections in 2006 and has not met fully since 2007, due to the split between Fatah and Hamas.
Hamas has fought three wars with Israel since 2008 and is considered a terrorist organization by the Jewish state, the United States and others.
In total, 12 members of the 132-member council are currently jailed by Israel, the Prisoners Club said.
