Teachers of different schools and colleges of Tangail formed a human chain in the district town yesterday demanding immediate arrest of the culprits who bludgeoned the headmaster of Bindubasini Government Girls' High School in the town on Tuesday last.

Several hundred teachers under the banner of Sammilito Shikkhak Sangram Parishad (SSSP) joined the programme at Nirala intersection in the morning and vowed to continue agitation until the culprits are arrested.

Sangram parishad convener Mohammad Abdul Karim, also the headmaster of Bindubasini Government Boys' High School in the town, said they got frustrated as police could not arrest any of the attackers even after five days of the incident.

He demanded security of the teachers and students of different educational institutions in the district. A three-member committee formed to probe the incident will submit its report on

September 12.

Mohammad Afsar Ali, headmaster of Bindubasini Government Girls' High School, was seriously injured allegedly by Bangladesh Chhatra League (BCL) activists onTuesday.

They entered the school at around 6:00pm and created pressure on Afsar Ali for admitting three students to the school. As the headmaster refused to do so, the intruders started beating him with hammers.

With serious injuries in his leg and jaw, and several teeth broken, the headmaster was brought to Tangail

General Hospital onTuesday evening. He was referred to Dhaka Dental College Hospital the same night.

Moriam Begum, mother of the victim, filed a case with Tangail Model Police Station the following day, accusing Tangail district BCL vice president Mostafizur Rahman Sohel and 6/7 others.

Protesting the brutal attack on Afsar Ali, teachers of the school and other institutions in the area brought out a procession in the town shortly after the incident.
