The road in front of the office was also a bit more crowded than in other days around 11:45am. Agitating lawyers were on their way to Shibbari crossing to join a protest rally against Tuesday's bomb attacks on Gazipur Bar Association building and Chittagong court.

Al Amin, a peon of the magistrate of the Speedy Trial Court, Gazipur, who was standing at the gate to help police identify office staff, witnessed the incident.

"I saw a youth who looked like a tea vendor coming towards the gate with a flask and a bucket in one hand and some cigarette packets in a polyethylene bag on the other," Amin said.

Another youth was following the "tea vendor" from a little distance, Amin told The Daily Star at Dhaka Medical College and Hospital (DMCH).

"I requested the policemen to body-search him as his movement seemed to be suspicious to me."

"Suddenly, he started running towards us and as soon as he pulled the flask cover, I heard a huge bang.

"As I collapsed, I heard the youth saying 'I will kill everyone', twice. This is all I can recall," Al Amin said with four splinters in his body.

Architect Abul Kalam Azad, owner of a building designing consulting firm in Gazipur, was about to board a rickshaw to return home finding the DC office closed.

"A youth appeared from the west and ran to the DC office gate. Soon I heard an ear-deafening bang. There were sparks of a fireball and smokes blowing up," Azad said.

Moments later, he found four to five people lying on the ground, one of them looking for something. Firefighters rushed in and showered water on the youth, he added.

In an interval of one day, a gloomy scene again descended on the DMCH as 19 of around 30 injured in the suicide attack were committed to the hospital.

An unidentified man in his forties succumbed to his injuries on the way to the DMCH.

The wounded started coming to the hospital on their own around 1:15pm. Doctors and nurses were ready for the situation, as the DMCH authorities had already been informed about the matter.

Doctors alleged a huge rush of family members, relatives, visitors and lawyers is hampering the treatments.

"At times we even could not reach the seriously injured patients, as they were surrounded by people," said a doctor showing apparent anger.

Lawyers from Gazipur and the Supreme Court also turned in to visit their colleagues.
