PKR Youth information chief Latheefa Koya said the evidence would be submitted to police and the Human Rights Commission (Suhakam), and be put up on websites and blogs.
Also present at the press conference was Ijok PKR candidate Tan Sri Khalid Ibrahim who gave an account of aggression he encountered during the campaign period.
Khalid said PKR campaigners were even stopped from entering some areas.
"A group of doctors who had set up a health clinic in Sungai Darah was stopped by the village head who said he was rooting for BN," said Khalid.
"Some of our campaigners were also not allowed to distribute leaflets because the police said we needed a permit." sun2surf
