The Delhi Police has identified three of the policemen who allegedly forced five men injured during the riots in northeast Delhi last year to sing the national anthem. One of those injured men later died.
The three personnel, posted with the Delhi Armed Police, will be put through a lie-detector test, the Indian Express has reported quoting sources.
The special investigation unit of the Crime Branch questioned more than 100 police personnel and scanned a number of documents, including duty charts of the policemen deployed from outside during the riots.
The incident which happened in February last year has been captured on camera.
