At least 50 people were injured in a clash between law enforcers and pro-BNP Jubo Dal and Chhatra Dal activists in Rupganj of Narayanganj yesterday afternoon as police barred their joint procession.

Of them, nine activists — five of Jubo Dal, youth front of the BNR and four of Chhatra Dal, the pro-BNP students' organisation — were hit by rubber bullets while 15 policemen were injured in brickbats.

The procession was organised to congratulate the newly-formed central committee of Chhatra Dal and celebrating the jail release day of BNP's Senior Vice-Chairman Tarique Rahman.

During yesterday's clash, vehicular movement on Dhaka-Sylhet highway remained suspended for around an hour.

Police arrested eight people from the spot for their alleged involvement in the clash.

The injured were admitted to Araihazar Upazila Health Complex and different local clinics.

Sheikh Nazmul Alam, district superintendent of police, said 15 policemen were also injured during the clash. Police fired around 200 rounds of rubber bullets and 50 tear gas shells to control the situation.
