A man who was arrested in connection with the death of Chrissie Treacy on her Portumna farm earlier this year has been released without charge.
Chrissie Treacy (75) was killed on her farm at Boula, Portumna when she was struck by an agricultural vehicle on April 27.
A man in his 50s was arrested on Tuesday morning and held by Gardaí at Loughrea garda station for questioning.
He was held under Section 4 of the Criminal Justice Act and released on Wednesday evening.
The investigating gardaí are preparing a file for submission to the Director of Public Prosecutions.

The State Pathologist and a team from the Garda Technical Bureau examined the scene for potential crimes scenes.
Gardaí questioned multiple witnesses at the time, of which the man detained this week was one.
