Ian Bailey's sister has told the High Court that a European Arrest Warrant meant he was unable to visit his dying mother in England.
Kay Reynolds described her brother's relationship with his mother as 'very sweet, tender and very gentle'.
She was giving evidence in his alleged wrongful arrest action over the murder of Sophie Toscan du Plantier.
Ian Bailey's only sibling Kay Reynolds gave emotional testimony describing his relationship with his mother before her death nearly two years ago.
She said her health began deteriorating around the time a European Arrest Warrant was issued for her brother which meant he couldn't travel to the UK to visit her without fear of being deported to France and winding up in a French prison.
She said she was very scared for him and thought it was very unjust.
Her mother's fragile health meant she couldn't talk to her son by phone and so Ian Bailey had to rely on the staff of the nursing home for regular updates on her wellbeing.
She said he was also unable to attend her funeral following her death in May 2013 but he wrote the eulogy and picked the hymns and poems.
Earlier today, A freelance photographer told the court that he photographed ex-soldier Martin Graham with cannabis in a 'garda evidence type of bag'.
Billy MacGill described meeting Mr Graham with a reporter in 1997 to try and verify his claims that detectives were giving him cannabis to get close to Ian Bailey.
The photographer says they watched the former soldier, who had been searched and given a recording device, get in and out of a white car in Skibbereen.
He says afterwards Martin Graham showed them cannabis in a clear plastic bag which he photographed.
The court heard the recording was distorted.
Former journalist Ian Bailey is suing the State and Garda Commissioner for alleged wrongful arrest over the 1996 murder of French film maker Sophie Toscan du Plantier.
