Gardaí investigating a fatal hit-and-run in county Donegal last month have released without charge a woman in her 20s.

The body of 48-year-old Alan McSherry was discovered on a road at Ardfarna in Bundoran in the early hours of Sunday August 25th.

The woman was arrested in Ballyshannon yesterday under Section 4 of the Criminal Justice Act.

She has since been released without charge and a file has been sent to the Director of Public Prosecutions (DPP).

Detectives believe Mr. McSherry may have been walking on a narrow unlit country road to his home at 4.40am when the incident happened.

His body was discovered at 5.10am by his wife as she drove looking for him.
