The Kajang by-election campaign is now under way and we want you to take part in our new crowd-sourcing project to document suspected electoral irregularities.

In previous elections, one of the priorities of Malaysiakini was to document election offences because we believe the media should be responsible in ensuring that competing candidates and their agents play fair.

However, Malaysiakini journalists can't be everywhere at once and thus we need your help to provide photographs, video clips and other evidence of foul play.

Once you've gathered the information, you can send it to us by filling up a simple web form and upload the evidence.

Information received will be scrutinised and published on a crowd-sourced map which will be updated daily.

Our journalists may contact the contributors to obtain more details about their submissions if necessary.

We hope this crowd-sourcing project will encourage more proactive and meaningful public participation in the democratic process.
