15-year-old boy shoots dead at least three students at Michigan high school and wounds six others including teacher

Three students are dead and six others - including five students and a teacher - are injured after a 15-year-old gunman opened fire at a Michigan high school Tuesday afternoon, days after students returned to school following the Thanksgiving break.

The suspected shooter, a sophomore at the school, was arrested within five minutes of the original call, police said.

'It's a very tragic situation, obviously,' Undersheriff Mike McCabe said during a press conference.

Senator Rosemary Bayer issued a statement shortly after the shooting, calling it 'horrifying.'

'The news of today's school shooting at Oxford High school is simply horrifying,' she tweeted. 'On top of an already difficult situation with the ongoing COVID-19 pandemic, our students now have to face this traumatic situation in a place that is supposed to be a safe space for students and growth.'

Police responded around 12:50 pm to a report of an active shooter at Oxford High School in Oxford Township, a suburb north of Detroit.

The suspected shooter was arrested and a handgun was recovered, said the Oakland County Sheriff´s Office, which added that it doesn't think there was more than one attacker.

Four to six people were wounded, but no fatalities have been reported, the sheriff´s office said.

'At this time it is still an active scene,' Undersheriff Mike McCabe told local media about 1:30 p.m.

'We have multiple patrol units and multiple EMS units on scene along with SWAT and Aviation Unit.'

Video footage from ClickOnDetroit shows a line of ambulances in the school's parking lot and a medical ambulance grounded on the rooftop.

A father on scene told Fox News that his son barricaded himself in a classroom when gunshots began ringing out.

The dad said his child is safe.

Democratic Rep. Elissa Slotkin of Michigan also issued a statement, expressing her own shock.

'I am horrified by the shooting at Oxford High School today,' she tweeted. 'I’ve been talking with Oxford leaders, parents and students and we are all praying for the health of those injured, and the well-being of all our young people, many of whom are in shock.'
