Gardai investigating alleged garda corruption have arrested a man as they continue their probe.
The civilian, from South Limerick, was arrested by gardai from the National Bureau of Criminal Investigation.
He is not a serving garda or a member of the garda staff - it is understood that he is involved in sport training.
He was taken by detectives to Thurles Garda Station where he was questioned and later released as a file is being prepared by the gardai.
A source said: "The man is an associate of a garda who was previously interviewed.
"The arrested man who has not been arrested before is involved in greyhound racing circles.
"This investigation centres around contacts between gardai and a crime gang in South Limerick - there is a part of the investigation that involves interactions."
A garda spokesman confirmed that the man was arrested and that it was part of a probe into corruption.
He said: "A male in his early 50s was arrested yesterday July 4, 2019 for suspected conspiracy to pervert the course of justice and detained at a Garda Station in Co. Tipperary under section 4 Criminal Justice act 1984.
"The male was subsequently released without charge and the investigations are ongoing.
"This arrest is in relation to investigations by personnel attached to the Garda National Bureau of Criminal Investigation (GNBCI) into alleged wrong-doing or corruption involving Garda personnel in the Southern Region."
