"We arrested Salahuddin Shoeb Chowdhury two days ago and subsequently sent him to jail to face a charge of financial cheating in line with a court directive," Dhaka metropolitan police's deputy commissioner Masudur Rahman told PTI.
Rahman said Chowdhury, who runs online Weekly Blitz, was arrested as a businessman named Sajjad Hossain filed a case accusing Shoaib of embezzling Taka 6.7 million.
In 2003, Chowdhury had been arrested when he was charged with spying for the Israeli intelligence agency Mossad while Bangladesh does not have diplomatic ties with Tel Aviv.
Two months back, Weekly Blitz created a stir when it carried a series of stories claiming that Pakistan President Asif Ali Zardari's son Bilawal was romantically linked to Khar. The report was dismissed as baseless though it went viral on the internet for several days.
Interestingly, the arrest of Chowdhury came a day before Khar's visit to Dhaka.
Khar visited Bangladesh on Friday, Nov 10. She called on Prime Minister Sheikh Hasina and main opposition BNP chief and ex-prime minister Khaleda Zia and held talks with her counterpart Dipu Moni.
