The chief suspect for the brutal Halloween murder of a 21-year-old man was hospitalised after he was given a severe beating in the early hours of New Year's Day.
The youth, who has close links to gangster 'Fat' Freddie Thompson, is the only suspect for the stabbing of Lorcan O'Reilly in the Oliver Bond flats complex.
Sources have revealed that a number of youths attacked the 15-year-old in Dublin's south inner city shortly after 4am last Friday and the teenager suffered a number of serious kicks and punches to the head.
He was brought to St James's Hospital where he was treated for a number of hours before being discharged.
"The teenager is lucky that his injuries are not an awful lot worse. This incident has led to an increase in tensions in the south inner city," a source said.
It is understood that some of those who were involved in the attack knew the murder victim and "there was an element of revenge about what happened".
After being savagely attacked, it has emerged that the teen is now being taken care of by relatives overseas.
Despite his tender age, the murder suspect was previously known to gardai and he was barely even a teenager when he was involved in a horrific gang attack in the Grafton Street area in which a man was badly beaten up.
However, the juvenile has now suffered the same fate and this has led to fears that criminals connected to 'Fat' Freddie's faction may now retaliate for it.
Last week, the Herald revealed that up to 16 people including a number of women and juveniles were questioned for withholding information about the murder of Lorcan.
He was stabbed to death at the Oliver Bond Street flats complex in Dublin at 2.45am on November 1 when he tried to break up a fight.
A chief suspect quickly emerged and he presented himself for questioning at Kevin Street Garda Station along with his two grandmothers a number of days after the stab attack.
However, officers declined to take a statement from the teenager as they intend to collect more evidence.
