A suspicious substance found on the underside of a desk in a Legislative Council meeting room has been identified as glue, according to LegCo president Jasper Tsang Yok-sing.

Lawmaker Kenneth Leung Kai-cheong had suggested that the substance might be faeces when he discovered that it had stained his shirt and trousers brown on Saturday. However, CCTV footage showed no-one entering the room nor any suspicious conduct before the meeting.

Tsang said both private and government lab results showed no bacteria consistent with faecal matter. Instead, the laboratories found traces of the material “urea formaldehyde”—an adhesive substance used in woodwork.

“We believe one possible explanation is that this adhesive substance was left io the furniture of the meeting room,” Tsang said. “I must say this is not conclusive but it seems to have ruled down the likelihood that it was caused by someone or that it was the result of a mischievous act.”

Tsang added that they found traces of similar substances in other seats of the room.

However, Leung said he still believes the substance had a faecal odour.

Lawmaker Kenneth Leung Kai-cheong found that his trousers and shirt were stained by some brown substance.

Urea formaldehyde does not have a distinct odour, and normally dries within a day,r Edmond Wong Hon-ping of the Department of Construction at the Hong Kong Institute of Vocational Education (Tuen Mun) told Apple Daily.
