Authorities in Bangladesh have arrested a key opposition figure from the Bangladesh Nationalist Party and sent him to prison after a nationwide strike led to violent clashes with security forces.Media reports said at least three civilians died in the violence, which included an arson attack in the nation’s capital, Dhaka, on Sunday.

Dozens of others were injured during the strike.At least one police officer was killed and scores were injured on Saturday when a massive rally by tens of thousands of opposition activists turned violent, police said.

The opposition is demanding the resignation of prime minister Sheikh Hasina and the transfer of power to a non-partisan caretaker government to oversee general elections next year.After almost nine hours in detention, police late on Sunday arrested Mirza Fakhrul Islam Alamgir, the secretary general of the Nationalist Party led by former prime minister Khaleda Zia, Hasina’s main rival, according to Faruk Hossain, deputy commissioner of the Dhaka Metropolitan police in charge of media.Hossain also said that 1,300 people were being investigated for Saturday’s violence.

Local reports said police had raided the homes of several opposition leaders overnight in Dhaka.Alamgir appeared before a magistrate court late on Sunday when his bail request was rejected and he was ordered to be sent to prison, pending further legal procedures involving charges of vandalism during Saturday’s violence.Police claimed a group of opposition supporters attacked the official residence of the country’s chief justice during Saturday’s protest.

Alamgir has been implicated in the case.The party denounced his detention and announced a three-day blockade of roads and public transportation across the country starting on Tuesday.Dhaka Metropolitan police Commissioner Habibur Rahman said that Alamgir was detained for questioning.

Under the law, he must appear in court within 24 hours.Home minister Asaduzzaman Khan told reporters that leaders of Zia’s party have to bear responsibility for their role in the violence, the United News of Bangladesh agency reported.Amid growing tension in a country dominated by the two major dynastic political parties of Hasina and Zia, the ruling party’s general secretary Obaidul Quader said on Sunday that there would be no dialogue with the opposition before the election unless it agrees with four issues, including the ruling out of a caretaker government.

The party is also demanding that Hasina remain the head of government until the election, and it rejects any changes to the Election Commission.On Sunday, at least three vehicles were set on fire in the capital as police increased security.The United News of Bangladesh agency reported that two people, including an opposition activist, were killed in Dhaka while a ruling party man died in the northern district of Lalmonirhat on Sunday.
