Gardaí are warning about sharing misinformation on social media about Ashling Murphy's murder investigation.
They say sharing false information is unhelpful in the criminal investigation into who killed the 23-year-old primary school teacher along the canal near Tullamore last Wednesday.
Officers are appealing for information about a man in the area dressed in a black tracksuit top, black tracksuit bottoms with a large white stripe or white writing on the side, and black runners to contact them.
