Police in Bangladesh say the son of former Prime Minister Khaleda Zia has been arrested as part of a wide-ranging anti-corruption crackdown.
Authorities say security forces Wednesday detained Tareque Rahman, the joint secretary-general of the Bangladesh Nationalist Party. Several other key political figures and a newspaper editor were arrested as well.
Witnesses also say the Dhaka home of Sheikh Hasina, another former prime minister, was raided, although no arrests were made.
The arrests were the latest in a series by Bangladeshi authorities of former ministers and politicians suspected of corruption.
The interim government says the crackdown on corrupt politicians from both main political parties is aimed at preparing Bangladesh for free and fair elections.
The caretaker government declared a state of emergency and suspended national elections in January following months of crippling opposition protests demanding electoral reforms.
