Egypt's Muslim Brotherhood has failed to implement its "political schemes" in the Gulf, Dubai’s police chief, Dahi Khalfan, has said.
Moreover, the Islamist group might conduct "fraud operations" to acquire Gulf currencies to solve Egypt’s economic crisis.
Khalfan’s comments on Twitter were reported on Friday by the UAE’s Al-Bayan newspaper.
"This is an expected scenario amid a financial crisis and fears of bankruptcy," he added.
Regarding the Egyptians arrested in the UAE for allegedly forming a Brotherhood-linked cell, Khalfan described them as ""tax collectors" who professionally steal money for their masters in the movement."
Khalfan has repeatedly launched verbal attacks against Islamist leaders in Egypt and Tunisia who came to power after the Arab Spring and accused Egypt's Brotherhood of planning to topple the Gulf monarchies.
"My sources say the next step is to make Gulf governments (their ruling families) merely figureheads. They will start with Kuwait in 2013 and move on to the other Gulf states in 2016," he told the Kuwaiti daily Al-Qabas in March.
Yasser Ali, spokesperson for President Mohamed Morsi, in July said the Muslim Brotherhood was responsible for answering statements by Khalfan, not the presidential office.
On 2 January, Morsi's aide for foreign affairs, Essam Haddad, the president’s secretary, Khaled Kazaz, and General Intelligence chief, Rafaat Shehata, went on a two-day visit to the UAE to deliver a message to the country’s leader, Sheikh Khalifa.
Before the visit, the Gulf state arrested members of an alleged Muslim Brotherhood cell working against the Emirati government. The reported cell included a number of Egyptians who had been working in the country for many years.
