Several Israeli soldiers broke into the family home early Monday morning and arrested 15-year-old Mohammed, said his father, Bassem Tamimi to the Associated Press.
The young activist broke his arm over the weekend as he fled tear gas flares launched by Israeli security forces during protests in his village of Nabi Salih, said the father, who suspected his son was taken in for throwing stones at Israeli soldiers.
The Israeli Defense Forces (DF) said the military arrested 21 Palestinians during the night for participating in 'riots' without giving further details, according to the AP.
Tamimi herself was held in an Israeli prison for eight months for slapping two Israeli soldiers, making her a symbol of young Palestinian opposition to the Israeli military occupation that has taken over the West Bank and other parts of Palestine since the 1967 Six Day War that forced some 600,000 Palestians from their rightful territories.
In a video taken of Mohammed's detention, Tamimi can be heard exclaiming: "Stop, I will beat you".
Several members of Tamimi's family, including her mother, have been arrested by Israeli authorities in their fight to recuperate their land being taken over by Jewish settlements.
