Ian Bailey's High Court action has heard he is still 'a person of interest' in the Sophie Toscan du Plantier murder investigation.
Retired Garda John Wilson is being cross examined about his assertion that up until 2012 the former journalist and his partner Jules Thomas were under a level of garda surveillance 'reserved for active criminal offenders'.
Under cross examination, Luan O'Braonain put it to the former garda that the du Plantier investigation was ongoing in the 2000s and that Mr Bailey remains 'a person of interest'.
Mr Wilson maintains the overall level of scrutiny was 'oppressive'.
Previously, the retired garda said a check of the Pulse system unveiled around 150 entries on Ian Bailey and his partner Jules Thomas.
Noted incidents included the couple having coffee in the English market and shopping in Super Valu.
John Wilson said he received no response when he made an internal complaint about the level of garda surveillance the couple was under.
He said that level of scrutiny is usually reserved for 'active criminal offenders' - a term he has been asked to define by lawyers for the State.
His cross examination continues today in Ian Bailey's damages action for alleged wrongful arrest in the Sophie Toscan du Plantier murder investigation.
