The Irish Times is reporting that a 20-year-old woman in Australia has been charged in connection with the death of a 17-year-old boy originally from Dublin.
She was allegedly driving a car which hit and killed Jacob Cummins in Perth last Thursday afternoon (7 December).
Four of Jacob's friends were also injured in the incident and one witness said that the teenagers were "scattered" over the road and face down in bushes following the crash.
Local online newspaper, WAToday, said that Jacob's death took place shortly after a fight between boys from two schools broke out nearby where two people suffered minor stab wounds.
Police have described the brawl that led to the death of the 17-year-old as a "school fight gone horribly wrong".
Around 100 people gathered at Perth's Scarborough Beach for a memorial service for Jacob where his family and friends were also in attendance.
State Control Acting Inspector Dean Snashall said: "What we are dealing with here is essentially a school fight that's got completely out of hand."
"It's an absolute tragedy that a school fight can get to a situation where we have a person deceased and several people injured.
"There's no evidence to suggest any gang involvement here, the group is six or seven different nationalities, it's a diverse range of people.
"This is school kids who have had an altercation over a school yard matter and unfortunately a young 17-year-old has paid the ultimate price."
