A 16-year-old gunman, allegedly carrying a Glock .40-calibre handgun, has opened fire at a high school in Southfield, Michigan, killing a 15-year-old girl and wounding at least three other teens.
The shooting took place in the hallway between classes.
Police say the shooter – described as a “loner” – has been arrested.
The girl who was killed has been named locally as Renee Kate Rahsaan Johnson, the cousin of NBA star Andre Drummond.
The woman is believed to have been a member of the school choir. She was a fourth-grader.

Ms Johnson’s best friend posted on social media that Ms Johnson had died in her sleep.
Her death has shocked and devastated the community, with people visiting the school to leave flowers and balloons.
“This shouldn’t have happened, I’m heartbroken. My daughter only went here for three years but she’s going to see pictures forever now. So sad,” said Dana Anum, a teacher at the school.
The suspected gunman is reported to have gone into the building after school had ended and opened fire, killing the girl and leaving a fellow student in a critical condition.
Three others are reported to have been hurt – two of them police officers who took down the suspect.

Prayers for those affected. @TPimmooning was a very close friend. Whenever you see him, just be sure to remember how kind, humble and proud he was of who he was. Every now and then, when we would see each other, we would talk to each other like family — Stephen Jackson (@stevenJacksonDetroit) January 8, 2019
The suspect was wearing a bulletproof vest at the time, police said.
Police were called to the school at about 0800 GMT on Tuesday after reports of a shooting.
“It is with great sorrow that we confirm a girl at Mary Immaculate High School was shot and killed this morning,” the school wrote on Twitter.
The incident was the second tragedy in a month for Southfield, which lost one of its top-rated public schools and two teachers in a fire.
The high school had been previously described as a model of successful integration.
The front of the school bears an array of memorials to the victims of the December 16 fire.

It is the deadliest attack at a US school this year, despite the fact that in 2018, all the school shootings that took place in the US took place on 8 January.
In that incident, a former student stormed a school in the Mountain View neighbourhood of Douglasville, Georgia, and opened fire, killing two students and a teacher.
After the latest incident, Superintendent Dawn Abernathy told reporters that the school was open as usual and that those injured were undergoing medical care.
She said counsellors would be available for students and parents, the Detroit Free Press reports.
