Jatiyatabadi Muktijoddha Dal president Ishtiaq Aziz Ulfat was arrest at Hazrat Shahjalal International Airport early Wednesday in a case filed in connection with Tuesday's clash between police and a group of BNP leaders and activists in front of the High Court.
Plainclothes police arrested Ulfat around 1:45am at the airport and then took him to Shahbagh Police Station, said BNP senior joint secretary general Ruhul Kabir Rizvi.
He said the Muktijoddha Dal president was scheduled to go to the USA.
On Tuesday night, a case was filed with Shahbagh Police Station against 500 people in connection with the clash.
Matiur Rahman, sub-inspector of the police station, filed the case against 20-25 identified and 475 unidentified people on charges of vandalism and assault on police, said Arifur Rahman, inspector of Shahbagh Police Station.
He said Ulfat was shown arrested in the case.
On Tuesday, two policemen were injured in a clash between a group of BNP leaders and activists and police while they were staging a demonstration in front of the High Court seeking Khaleda Zia's release.
A number of vehicles were also vandalised during the clash.
Ulfat along with some BNP leaders took part in the demonstration carried out under the banner of Jatiyatabadi Muktijoddha Projonmo Dal.
Meanwhile, BNP senior joint secretary general Ruhul Kabir Rizvi on Wednesday denounced the case failed against their party leaders and activists.
Speaking at a programme at the party's Nayapaltan central office, he said their party men staged the demonstration in front of the High Court exercising their constitutional rights.
Rizvi warned that the government will not be able to suppress the nationalist forces by using the law enforcers.
