TBH-ADA chairman Ng Yap Hwa said the Brickfields police headquarters called him and fellow members, Wong Yan Ke and Wong Voon How, to give their statements at 5.30pm today.

Ng said the group would also lodge a report at the same station alleging police violence.

On Monday, at the climax of the group’s “walk of justice”, a handful of members tried to gain access to Parliament and were intercepted by police. There was a brief scuffle, during which Teoh’s sister Lee Lan fell to the ground and was apparently hurt.

Ng also claimed that one woman – a member of the demonstration’s organising committee – was grabbed at the collar by a policeman, which broke her necklace and left red marks on her neck.

After a brief stand-off, the group was able to submit the memorandum but could not enter the building as originally planned.

Ng said the group planned to bill the government and request compensation for the damage to the necklace and medical treatment.

On May 5, the group launched a campaign called The Search for Missing Prime Minister Anwar Ibrahim in Kuala Kubu Bharu, following multiple failed attempts by the family to meet Anwar since he took office.

In 2009, Teoh, the former aide to then Selangor executive councillor Ean Yong Hian Wah, was found dead on the fifth floor of Plaza Masalam in Shah Alam, hours after he arrived for questioning on the 14th floor of the Selangor Malaysian Anti-Corruption Commission headquarters.

A coroner’s inquest in 2011 delivered an open verdict, and his family subsequently filed an appeal against the findings. Three years later, the Court of Appeal set aside the open verdict and ruled that Teoh’s death was caused by multiple injuries as a result of unlawful acts by unknown persons.
