A woman has described seeing a bus driver and another woman trying to save the 15-year-old girl who was stabbed to death in Croydon.

Footage posted on social media showed several police cars and ambulance vehicles near a bus in Croydon on Wednesday morning (September 27).

Both the land and air ambulance attended but she was pronounced dead at the scene 50 minutes later.

Around an hour and 15 minutes after the stabbing police arrested a teenage boy in connection with the girl’s death.

The woman, a mother-of-two who only wanted to be known as Bridget, said she saw the two people trying to resuscitate the girl on the pavement at about 8.30am.

She said: “I was on the bus before and came off and walked back down, I saw them resuscitating her.

“The driver was holding her and a lady.

“The emergency services were already here when I walked back.”

Chief Superintendent Andy Brittain said: “Our immediate thoughts are with this young girl’s family who are facing the most tragic of news. Our officers are with the girl’s family to support them.

“I am in contact with the local community, who are clearly as concerned as we are about this tragic incident. I shall continue to update them throughout the day.”

Mayor of London Sadiq Khan said he was “absolutely heartbroken” at the news of the girl’s death.

Emergency services were called to Wellesley Road in Croydon at around 8.30am to reports that the girl had been stabbed.

Both the land and air ambulance attended but she was pronounced dead at the scene 50 minutes later.

Around an hour and 15 minutes after the stabbing police arrested a teenage boy in connection with the girl’s death.

Mr Brittain added: “My officers were immediately on scene to provide first aid and support paramedics.

“Acting on information provided to them, officers also worked closely with colleagues from across the Met and the British Transport Police to track a teenager in connection with the stabbing.

“I can confirm that an arrest was made at about 9.45am in the Croydon area. At this early stage we believe that he may have known her.

“A crime scene will be in place for some time, and I am grateful for the co-operation of residents.”
