The man accused of the murder of Detective Garda Colm Horkan is due back in court this morning.
A medical update on Stephen Silver, of Foxford, Mayo, is also set to be outlined at Harristown District Court this morning.
The 43-year old mechanic was due to appear in court a fortnight ago but on that occasion, Judge Alan Mitchell was told that he was unfit to appear.
He was due to appear via video link but the court heard he was not well enough to do so as he was receiving treatment at the Central Mental Hospital.
His defence solicitor Gearoid Geraghty said it needed to be established why his client was being detained there.
The court also heard on the last occasion that the case was 'advancing at rapid speed' and that 'numerous detectives and senior officers' were working on it.
Judge Mitchell remanded Silver in custody until today and also requested a letter from the governor of Castlerea Prison outlining why the defendant was transferred to Midlands Prison and to the Central Mental Hospital to be prepared ahead of today.
