Pedestrians initially took Ahmed to a local hospital but he was later transferred to Suhrawardy Medical College Hospital where the doctor on duty declared him dead.
“He was stabbed in the lower part of his thigh. The doctors in the first hospital could not determine the severity of his injury as the wounds were covered up by his trousers," said Mahtab.
Ahmed died due to excessive bleeding, he added.
The body is being stored at Suhrawardy hospital's morgue. Police are investigating the incident, Mahtab said.
