A 16-YEAR-OLD GIRL who died in a hit-and-run in Navan, Co Meath has been named as Mia Lily Keogh O’Keefe.

The young girl was killed after being struck down while out walking with her dog on Saturday evening after 8pm on the Slane Road in the town.

The driver fled the scene but a man in his 20s has since been arrested by investigating gardaí.

In an update this morning, a garda spokesperson has confirmed that the man has been released without charge and a file will be prepared for the Office of the Director of Public Prosecutions.

More than €21,000 has been raised on GoFundMe to support Mia Lily’s family after the teenager’s death.

It came as part of a horrific weekend on Ireland’s roads, with Mia Lily’s death one of seven over the past two days in crashes in Tyrone, Galway and Waterford.

A further six people were injured across the incidents.
