Is this what you’re referring to:
1. In 1627 Heller was called to the chief rabbinate of Prague. On account of the Thirty Years’ war the government imposed heavy taxes on the Jewish communities of Bohemia, including that of Prague,which had to pay a yearly tax of 40,000 thalers. As Heller was the chief rabbi he was compelled, against his will, to preside over the commission which had the task of apportioning that sum among the members of his communities. Although he acted with the greatest conscientiousness, some complained of unfair allotment. They accused Heller and the elders of the commission before the civil authorities of having spared the rich and laid the burden of the tax on the poorer people.

2. Several factors account for Heller’s imprisonment. His arrest marked the beginning of a brief Habsburg anti-Jewish campaign, encouraged by the Papacy. Heller also had enemies within the Prague Jewish community. On account of the Thirty Years’ War, the government had imposed heavy taxes on the Jewish communities of Bohemia, including that of Prague, which had to pay a yearly tax of 40,000 thalers. A commission headed by Chief Rabbi Heller unanimously voted to tax each Jewish family in Prague. The richer the family, the higher the tax. The burden fell mostly upon the rich merchants who could well afford to pay their assessments. However, they complained and demanded a reexamination of the decision. R’ Heller and his committee reviewed the problem and concluded that this approach was fair. The committee met with representatives of the merchants’ association to explain the sensitive situation facing the Jewish community of Prague. The irate merchants refused to deal with the Kahal which was responsible for delivering the money to the government. Instead, they decided to appeal to the government. In their petition they charged the Chief Rabbi with being an enemy of Christianity. Their proof: “His writings are filled with allegations against the religion of the country. R’ Heller was associated with the wealthy leader of the Prague community at that time, Jacob Bassevi, and bore the brunt of anger against him. Meanwhile, Bassevi, who was an ally of the great general Albrecht von Wallenstein, also had enemies at the Habsburg court, and the arrest of Heller played a part in larger political machinations there.

Three different historical accounts, but none of them relate in any way to the discussion here!
