DU unit General Secretary Hemayet Uddin Khan Himu and activist Nazmul took first aid at Dhaka Medical College and Hospital. The other injured are Suryasen Hall unit Organising Secretary Kamruzzaman Shohag and activist Shahin.

The BCL formed a two-member committee with BCL President Liaqat Sikder and General Secretary Nazrul Islam Babu at an emergency meeting at its central office at Bangabandhu Avenue to investigate the incident.

Emerging from the meeting Babu said that they would take punitive measurers against the persons responsible for the incident within 72 hours.

Party sources said the DU unit committee might be dissolved within a couple of days following the intra-party feud. The tenure of the one-year DU unit committee ended at least two years ago.

Tension has been running high among the two factions of the BCL. Party insiders said violent factional clash can erupt on the campus at any time.

Witnesses said a group of angry BCL activists loyal to DU President Delwar Hossain attacked the pro-Himu activists yesterday with sticks in a sequel to earlier clashes.

They beat up Shohag as he violated the order of Delwar. Earlier, Delwar asked him not to take part any organisational activists due to his mugging blame. In retaliation, the activists loyal to Himu beat up another activist loyal to Delwar at the Curzon Hall area.

Meanwhile, panic gripped the students of DU after the two factions took position on the campus. Delwar along with his activists took position at the Mall Chattar area while Himu at the Curzon Hall area.

Delwar said, "General activists of the Chhatra League beat up a mugger as he tarnished image of the party."

Himu said, "I don't believe those who attacked me are BCL men."
