A Jatiyatabadi Chhatra Dal leader of Dhaka University was critically injured in an attack by some leaders and activists of Bangladesh Chhatra League on the campus on Friday night.

Later, the BCL leaders handed the victim, Shipan Biswas, who is joint convener of Salimullah Muslim Hall unit of JCD, and at least four of his friends to police, witnesses said.

Police took him to Dhaka Medical College Hospital from where he was shifted to a private hospital in Mouchak.

Shipan told The Daily Star that the attackers hit him in the face and ears with bricks and beat with sticks at the fine arts faculty.

HM Abu Jafar, member secretary of the dormitory unit of JCD and other leaders alleged around 20-25 BCL activists led by Obaidul Kabir Rikto, general secretary of fine arts unit of BCL, attacked him while he along with some of his local friends were visiting the campus.

DU Proctor AM Amzad said, "A JCD leader of SM hall and other 10-12 outsiders entered the fine arts faculty. Although police detained four of them at first, I have told police to release them if any case was not filed against them earlier."

About the attack, he said, "If they (JCD leaders) submitted any written statement to me, I will take necessary actions against the perpetrators."

Obaidul Kabir said, "Some 15 to 20 suspicious youths entered the fine arts faculty at night. We handed over six of them to Shahbagh police while the others managed to escape. Although some BCL activists beat Shipon up, I myself told police to take him to hospital."

Khalid Hasan Robin, president of fine arts unit of BCL, said, "I haven't heard the news earlier."

Rajib Ahsan and Md Akramul Hasan, central president and general secretary of JCD respectively, in a press release, protested and condemned the attack and demanded trial of the perpetrators.

Abid Al Hasan, president of DU unit of BCL, said, "I have heard the news. Rikto is one of my followers, I will take actions after knowing the details."
