Gardaí in Dundalk are investigating the care provided to an elderly woman, who died last month.
A garda spokesman confirmed that they were alerted by medical staff who were concerned about the woman's condition on her admission to Our Lady of Lourdes Hospital in Drogheda.
She was an in-patient for a number of weeks before she passed away.
It is understood the woman was underweight and had a number of bedsores.
It is also understood the woman, who was from Dundalk, had been living with a family member and was not in a nursing home.
"We will be talking to the people who looked after her in hospital as well as to family members," the garda spokesman said.
Gardaí are liaising with the Health Service Executive and carrying out an investigation into her care before her death.
They did not interview the woman.
A post-mortem examination was carried out and an inquest will be held at a later date.
A spokeswoman for the HSE said: "While the HSE does not comment on any individual, we can advise that the HSE always cooperates with gardaí when required to do so."
