Ireland's police chief resigns 2 months after calling corruption whistleblowers 'disgusting'

Ireland's police chief has resigned following months of criticism of his force's handling of allegations of illegal wire-tapping and corrupt enforcement of traffic laws.

Commissioner Martin Callinan made his surprise announcement Tuesday as Cabinet ministers discussed whether he should be expected to apologize for calling the actions of two police corruption whistleblowers "disgusting" in comments to a parliamentary committee two months ago.

Callinan, Ireland's senior law-enforcement officer since 2010, previously denied that his force was responsible for the suspected bugging of telephones inside an independent agency that investigates complaints against the police force.

One key active investigation involves alleged manipulation of Ireland's system for imposing penalties on law-breaking drivers. Two whistleblowers have accused fellow officers of helping celebrities, politicians and friends to make their traffic tickets disappear.
