THE chief suspect for a brutal assault on a retired garda who died earlier this week has provided a full statement to detectives.
The suspect has provided details about last weekend's violent incident at a west Dublin house.
A major investigation is taking place into the death of former Garda Seamus Marren (54), who previously served at Cabra, Clontarf, Bridewell and Monaghan town garda stations, before his retirement two years ago.
The Irish Independent has learnt that Mr Marren was savagely assaulted in a house in Clonsilla last Saturday and suffered a broken leg as well as serious head injuries.
He was rushed to hospital and medics placed staples in his head to stem the blood flow.
However, he passed away on Thursday afternoon.
Last night, the house where the assault happened remained sealed off as a garda forensics team carried out a technical examination of the property.
He was attacked twice in two serious incidents in the sitting room and hallway of the house after an argument developed over a long- standing issue, sources have confirmed.
The assault is believed to have lasted for a few minutes and left Mr Marren with very serious injuries.
A 24-year-old man, who is well known to Mr Marren, was questioned for a number of hours by gardai at Blanchardstown garda station on Thursday evening.
He spoke to detectives voluntarily and was not arrested. The west Dublin man is not known to gardai for any involvement in crime and is a working man with a young family.
The deceased former garda from Lohunda Downs, Clonsilla, was admitted to Connolly Memorial Hospital on Saturday but was discharged on Sunday; however, he continued to feel unwell and had been bedbound all week.
He fell unconscious at around 3pm on Thursday.
The emergency services were called but he was pronounced dead by the time he got to hospital.
Deputy State pathologist Dr Khalid Jaber was still conducting a post-mortem on Mr Marren's body last night with gardai stressing that the results of the examination would decide what direction their investigation would take.
A source explained: "The key thing here is establishing what was the cause of death – what is not in doubt is that the injured party suffered a very serious assault last weekend.
"At the moment this is being treated as a suspicious death, but that could be very much upgraded depending on the results of the post-mortem."
Mr Marren was a popular garda, who was considered a private and respectable man.
