A Bangladeshi politician has been detained in prison for a further 30 days following his arrest last month.
Jalil's lawyers stressed their client's ill health
Abdul Jalil, the secretary general of the Awami League, was arrested during a continuing anti-corruption drive.
Dozens of top politicians have been detained since a state of emergency was declared in January.
It was declared by the military-backed caretaker administration which also suspended parliamentary elections that had been due in January.
It says it will hold the polls by late 2008, giving it time to deal with Bangladesh's endemic corruption.
A court in Dhaka ordered on Sunday that Mr Jalil should remain in custody for further questioning on charges of corruption and misuse of power.
Mr Jalil's lawyers asked the court to order the prison authority to pay particular regard to their client's poor health.
At least 60 members of parliament and former ministers face questioning under the state of emergency declared by the military-backed caretaker administration which took over in January.
The BBC correspondent in Bangladesh says the two rival former prime ministers, Sheikh Hasina and Khaleda Zia, are looking increasingly isolated as many of their closest colleagues disappear behind bars.
Awami League leader Sheikh Hasina has denounced the latest detentions, saying they were an "autocratic move... directed more against politicians than corruption".
Sentenced in absentia
Last week, one of the most important figures in Khaleda Zia's government was given a three-year jail sentence.
Harris Chowdhury was found guilty by a special anti-corruption court set up by the interim government.
The sentence was imposed in absentia as he is in hiding. It was the first such sentence against a high-ranking politician.
The interim government has made tackling corruption its main objective.
Among the many prominent people under arrest is Ms Zia's influential elder son, Tarique Rahman. He was detained in March, accused of extorting $147,000 from a construction company. He has denied wrongdoing.
