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 Gardaà at Loughrea garda station for questioning.
He was held under Section 4 of the Criminal Justice Act and released on Wednesday evening.
The investigating gardaà are preparing a file for submission to the Director of Public Prosecutions.
Chrissie Treacy lived alone on her family farm near Portumna, where she was struck by a teleporter vehicle before being found dead on the afternoon of April 27.
The State Pathologist and a team from the Garda Technical Bureau examined the scene for potential crimes scenes.
Gardaà questioned multiple witnesses at the time, of which the man detained this week was one.
The Gardaà have said they are pursuing multiple lines of inquiry.
