A HERO schoolgirl was killed on a bus to class when she stepped in to protect her pal from an ex-boyfriend.
But what exactly happened to Elianne Andam? Here's everything we know...
Who is Elianne Andam?
Elianne Andam, 15, was a student at Old Palace school.
A spokesperson for Elianne's family said: "Our hearts are broken by the senseless death of our daughter.
"Elianne was the light of our lives. She was bright and funny, with many friends who all adored her.

"She was only 15, and had her whole life ahead of her, with hopes and dreams for the future.
"All those dreams have now been shattered. Our lives have fallen apart, along with that of our wider family."
Her aunt also Marian told how “she had a bright future ahead of her”.
She said: "She was a lovely girl, loved doing her hair. She wanted to be a lawyer, and she was at a private school paid for by my sister.”
Anthony King, chairman of My Ends - a project helping combat youth violence in Croydon, added: "She had a bright future ahead of her. She was in her GCSE year."
Mr King described the girl as an "absolutely incredible young lady" and told of how others said she was "jovial, very comedic".
What happened to Elianne Andam?
Elianne was knifed to death in Croydon after a boy tried to give his former girlfriend flowers and a love note on the No60 double-decker.
She was returning a bag of items after they separated recently, but a row broke out and he raced after her at a bus stop.
The boy is said to have pulled out a foot-long, serrated zombie knife and stabbed Elianne when she leapt to her pal’s defence on Wellesley Road in Croydon on Wednesday, September 27.
Both the land and air ambulance rushed to the scene but she was pronounced dead at the scene 40 minutes later.

Around an hour and 15 minutes after the stabbing, police arrested a teenage boy in connection with the girl's death.
On Friday, September 29, cops charged a 17-year-old boy with her murder.
Security worker Victor Asare described the horrific scene, adding: “A lot of people came, everyone came off the bus.
“(The suspect) ran. Everybody was crying and screaming. The girl was on the floor.
“We tried to catch him and a lot of people tried to save the girl. I was so shocked, I was shaken. It’s somebody’s daughter.
“I finished work but couldn’t sleep so came back. I wanted to see if the girl was OK.”
He said the girl, who was in a green blazer, looked as if she “didn’t want the boy to come closer” before he stabbed her with a knife “black, thin and about a foot long”.
Her family rushed to the scene in Croydon, South London, but she died 50 minutes after the 8.30am stabbing.
The suspect fled to New Addington five miles away where he was arrested on a tram.
