Politicians advised to avoid leaving or returning home at exactly the same times

It comes after it emerged newly appointed junior minister Jennifer Carroll MacNeill has been harassed by a second man.

Fresh security advice to politicians has encouraged them to consider a personal alarm and to vary their routine, including travelling to work.

The information was sent to all members of the Oireachtas on Monday via email and included personal security advice from An Garda Síochána. The email, seen by the Irish Examiner, said the information was being circulated following a security incident last week involving two members of the Oireachtas.
