Allegations against the suspects include paying hundreds of thousands of shekels annually in salaries without reporting to tax authorities, tax evasion amounting to millions, and money laundering between Israel and the United States, and possibly other countries.
Yeshiva World has more information on the Eidah Charedis money laundering, tax evasion and embezzlement arrests:
Authorities are signaling that the arrest of a number of Eida-affiliated askanim [activists] in Yerushalayim [Jerusalem] on Sunday morning is not the end, but the beginning of the case which involves tax evasion and money laundering to the tune of millions of new Israeli shekels. Officials announce with confidence that additional arrests are to be expected.
Five of the six suspects taken into custody…are…notables among the Eida Chareidit tzibur [community].
…Investigators report the tzedaka [charity] [used for the alleged frauds] had an annual turnover of tens millions of shekels…in…funds collected in and out of Israel in the form of cash and monthly ‘horat keva’ [fixed amount automatically repeating donations] bank-ordered deposits.…the funds were supposed to assist those in need, including orphans and young couples seeking to acquire a home. They used the names of prominent rabbonim [haredi rabbis] to enlist [solicit] funds.
The money from the Vaad Artzi was initially deposited in the Meah Shearim branch of Mercantile Bank, and of late the money was moved to a Poalei Agudas Yisrael bank in Bnei Brak. That branch was used for the alleged illegal activities authorities report.
Allegations against the suspects include paying salaries without reporting to tax authorities to the tune of hundreds of thousands of shekels annually, tax evasion amounting to millions, and money laundering between Israel and the United States, and possible other countries.
Investigators also allege two of the suspects involved used some of the tzedaka funds for their own personal use.
"Money laundering between Israel and the United States, and possible [sic] other countries."
I think this may turn out to be the key crime, one that may expose Eidah's payment of street thugs and its financing of violence and crime, and the names of the Diaspora haredim who help them do it.
