ITV News' Aisha Zahid has the latest from the scene in east London
A teenage boy has been arrested on suspicion of murder after a woman was shot dead in east London.
Lianne Gordon, 42, was killed in the attack in Hackney on Tuesday evening and a 20-year-old man and 16-year-old boy also suffered gunshot wounds, but have since been discharged from hospital.
The Metropolitan Police said a 16-year-old youth was detained in the early hours of Friday morning and remains in custody.
Detective Chief Inspector Jo Yorke, from the Met’s Specialist Crime Command, said: “While this arrest marks a significant development in this investigation, I would like to reiterate my appeal for anyone with information to come forward.
“I have a team of dedicated and experienced officers working tirelessly to ensure Lianne’s family and friends get the answers they so desperately need; if you can help then please get in touch.”
Police say they think the incident could be gang related.
Ms Gordon, who neighbours say may have been trying to protect her children during the shooting, died at the scene.
It is understood that she'd arrived home from a family holiday on the day before the shooting.
Three people were found with gunshot wounds. Two other people, a 20-year-old man and a 16-year-old boy, were taken to hospital for treatment before being discharged.
The Met Police are urging anyone with information to get in contact with them, or crimestoppers.
