On Tuesday night, Police Commissioner Stephen Lo Wai-chung said the young man who was arrested held “a sharpened object” and attacked an officer on the ground together with other protesters.

During the police press conference on Wednesday, deputy commissioner Chris Tang Ping-keung said the student held an “iron pole” when he attacked an officer.

But various video footage captured by local media outlets shows that the student surnamed Tsang, was wielding a white “pole-like object” when he hit the arm of the police officer who pointed his gun at two other protesters.

People believe it was not an “iron-pole” or a “sharpened object” as the police top brass have claimed.

After being shot in the chest, Tsang collapsed on the ground while holding the white pole.

Another protester came forward and tried to take the white pole but failed – he was subdued by another policeman.

The white pole then fell on the ground next to Tsang, who began asking for help as blood started coming from his chest. It was several minutes before a police officer checked his status and received first-aid treatment some minutes later.

Video footage shows police in plainclothes collecting evidence at the scene. An officer in a white-T-shirt seized a blue swimming board that Tsang used as a shield, plus a helmet and face mask.

Then when a riot police officer tried to pick up the white pole on the ground next to Tsang, then another officer in a black T-shirt passed him a longer, darker colored pole.

The cop in the white T-shirt held these weapons and left. But more footage from local broadcaster nowNews and CableTV shows that the white pole was still lying on the ground when Tsang was sent to hospital after police had cordoned off the scene.

When the reporters returned to the site an hour later, the white pole was gone.

Ming Pao Daily quoted an unmanned police source as saying that the white pole is an “iron pole”, adding that evidence collected by police at the scene aimed to show “the riot scene”, and the evidence may not be directly linked with the arrested student.
