The HSE have said staff are Garda vetted - but didn't comment on health worker Declan Power who this week emerged as a child predator jailed in the UK.
Sicko Power (58), from Dromiskin in Co Louth, was sentenced this week to two years and four months at Exeter Crown Court for child grooming offences.
It was claimed in Exeter Crown Court on Monday that Power worked as a health worker in Dundalk.
