Two teenagers remain in custody after they were arrested in connection with a stabbing yesterday evening.

Police were called at 8.02pm to reports of a teenage boy with a stab wound in The Ridgeway, St Albans.

The ambulance service attended and the boy was taken to hospital.

He was later released and returned home.

Firearms officers, supported by the dog unit and National Police Air Service, conducted arrest enquiries at addresses in Welwyn Garden City, London Colney and St Albans.

Residents in the Panshanger area took to social media after hearing the police helicopter overhead.

A 16-year-old boy from St Albans and a 15-year-old boy from London Colney were subsequently arrested on suspicion of grievous bodily harm and remain in police custody.

Sgt Caro, of the St Albans Safer Neighbourhood Team, said: “Despite some reports that are on social media, this is not connected in any way with Sandringham School.

“This is believed to be an isolated incident where the victim and suspects are known to each other and enquiries are continuing.”

Any witnesses who have not yet spoken to police or anyone with information is asked to contact Hertfordshire Constabulary on the non-emergency number 101, quoting crime reference 41/16207/19.
