A medical board was formed for his treatment.

Earlier, on Tuesday, a High Court Division had directed the Government and the inspector general of the police to immediately ensure health examination and treatment of the detained photographer at the BSMMU.

The award-winning photographer was picked up by the detective branch of police and kept him in detention a day after he gave an interview to Al Jazeera, criticising the Government for its role in tackling the current students' protest against road rage in Bangladesh.

According to media reports, a case has been filed against him under Information and Communication Technology Act. He has been in a seven-day police remand.

Meanwhile, Raghu Rai, another internationally famed photographer, has urged Prime Minister  Sheikh Hasina to release Alam and  ‘not to teach’ the agitating boys a lesson.

Rai who was honoured as a Friend of Bangladesh by the government in 2012 for his depiction of the War of Liberation, has said in his letter that his heart bleeds over the "arrest and torturing" of acclaimed photographer Shahidul Alam.

Rai described Alam as "a great admirer of country’s founder president Sheikh Mujibur Rahman and one of those rare breeds committed to truth and honesty, who can die for Bangladesh."

Earlier in the week, criticising the Bangladeshi government for Alam's arrest, top human rights watchdog, Human Rights Watch, said: "Authorities should order an immediate investigation into reports that renowned photographer and activist, Shahidul Alam, was beaten while in custody."

Brad Adams, Asia director at Human Rights Watch, said: “The authorities should immediately release anyone, including Shahidul Alam, they have locked up for peaceful criticism. Instead, authorities should prosecute those, including members of the ruling party’s youth supporters, who are attacking children with sticks and machetes.”

Thousands of students, including school children, have been blocking streets to protest the July 29 killings of two students by a speeding bus.
