A man has been beaten to death at Shaheed Suhrawardy Medical College Hospital on suspicion of being a child abductor.
The family of the deceased, 41-year-old Alam Sheikh, claims that he was mentally unstable.
The incident took place on Wednesday night at the hospital, said Tejgaon Division Police Deputy Commissioner Ibne Mizan.
He said that the police have contacted the family of the deceased and they claim that he was mentally unstable.
Adding that one person had been detained, Ibne Mizan said, "We have detained the mastermind of the incident. The family of the deceased has been informed that a case will be filed against him."
However, he could not provide details of the arrest.
Police said that Alam Sheikh had been roaming in front of the children's ward of Shaheed Suhrawardy Hospital in the capital's Mirpur around 11PM on Wednesday and the families of children undergoing treatment at the hospital grew suspicious of him.
When they asked Alam Sheikh why he had come to the hospital, he was reportedly unable to give a 'satisfactory answer'.
