The 10-minute video, comprising different clips, was used to help identify the shoes of the suspect in the robbery that killed the Pakistani security guard, Khan Zafar Iqbal.

The Coroner's Court was shown yesterday a picture captured from a homemade video dated December 30, 2000, showing a man wearing a pair of Mizuno sports shoes playing with a girl. The video was not taken inside the bank, but at home.

But the details of the video and the identity of that man were not disclosed in yesterday's inquest. Coroner's officer Arthur Luk said the source of the video would be explained today.

More details about the suspect of 2001 Hang Seng Bank heist will be revealed today as a video will be played in the Coroner's Court.

Wong Kwok-tung, a solicitor helping dead constable Tsui Po-ko's mother Cheung Wai-mei, said outside the court that police had seized a lot of materials from Tsui's home in Tung Chung after the Tsim Sha Tsui shoot-out last March, including slippers, photo albums and videos.

Tsui had allegedly killed constable Tsang Kwok-hang in the shoot-out, and was the alleged suspect behind the killing of constable Leung Shing-yan and Khan in 2001.

Pang Wai-hung, a manager of the sports shoe brand, testified yesterday that he believed the robber wore a pair of their shoes by looking at the pictures taken during the bank robbery.

He said the shoes worn by the man in the picture captured from the home video to be played today were the same style as the pairs of the robbers, but he was not sure whether the colour of the two pairs were matching.

Pang will continue his testimony today, further identifying the shoes by watching the bank's surveillance video and the homemade video.

Government chemist Cheung Kwok-keung testified that several shoe prints of the suspect were found in the bank counters.

He believed the shoe prints were left while the suspect was escaping as they faced towards the bank entrance.

He believed that the suspect was wearing a pair of Mizuno shoes sized between 27 and 28 in Japanese measurement, but most likely 27.5.

Retired senior forensic firearm examiner Andy Choi testified that three pieces of bullet fragments were found inside the bank.

He said these bullets were the same type used by the police force.

The bullets used to kill both Leung and Khan were from the same weapon as they carried same striations mark, which were unique for each individual barrel. The weapon was a 0.38 calibre service revolver, same as used by police.

Choi explained that the police would store guns and bullets of undetected crimes in its outstanding crime index database for future evidential task and comparison.

He said Khan did not fire his Remington rifle, even though one bullet was in the firing chamber and two were in the magazine under the barrel.

He said Khan did not disengage the safety catch of his gun, a step necessary for firing.

Chan Tsz-wah, a medical officer at Yan Chai Hospital, said Khan might have already died before being sent to the hospital.

Pathologist Lau Ming-fai said Khan was fired at his back head. The bullet penetrated the brain and was found underneath the forehead.

He got another gunshot at his abdomen, which damaged his intestine which was not fatal.

The shot to his left hand was missed after the bullet was blocked by Khan's watch, but the metal fragments caused a 5 X 1.2 centimeters and 60 millimeter depth wound.

The inquest into the death of Khan is expected to be completed today, after which examination of the Tsim Sha Tsui shoot-out proceeding will begin.
