Israeli authorities have arrested Omar Barghouti, co-founder of the anti-Israel Boycott, Divestment and Sanctions (BDS) movement, for evading taxes on $700,000 of his income.

The Israeli business news outlet Globes reported that Barghouti “is suspected of evading taxes on some $700,000 that he earned between 2007 to 2017 while serving as the director of the Ramallah-based National Computing Resources, which markets and rents ATMs and other technology within the Palestinian Authority.”

The BDS founder, who lives in the Israeli city of Acre, had attempted to conceal his income from authorities by hiding money in a bank based in Ramallah. According to the charges lodged against him, Barghouti also allegedly hid income that he earned from book royalties and a global speaking tour in a U.S. bank account.

The Israel Police supported the charges against Barghouti with transaction records and credit cards discovered at the BDS founder’s residence.

Following an interrogation by authorities in Haifa, Barghouti was released on bail, but is subject to a travel ban and cannot leave the country.

Barghouti has advocated for the destruction of Israel, saying in 2013, “We are witnessing the rapid demise of Zionism, and nothing can be done to save it…I, for one, support euthanasia.”
