A man was taken to hospital in a life-threatening condition this morning after a suspected stabbing in a Letchworth alleyway – which remains cordoned off.

Six police cars and two ambulances were called to Glebe Road at 7.40am after reports of a stabbing, with a passerby telling the Comet an armed response unit was also on scene.

An ambulance spokesman said a man in his 30s was taken to Lister Hospital in Stevenage in a ‘life-threatening’ condition with suspected stab wounds, but he is now believed to be stable.

The alleyway between Glebe Road and Cromwell Green has been taped off.

A police spokeswoman said: “Investigations are continuing, but it is believed to be an isolated incident between parties known to each other.

“A man has been arrested in connection with the incident and enquiries are continuing to trace a second man.”

A neighbour told the Comet: “My 18-year-old old daughter heard shouting. We’ve recently brought a house away from this area – I was dismantling a bed and found all this craziness!”

A motorist who passed the scene this morning added: “The alleyway between Cromwell Green and Glebe Road, about halfway along the latter, is cordoned off with police tape.

“There are several police cars on Glebe Road and a couple more police cars stopped at the top of Cromwell Green, which is a small cul-de-sac. It looks serious.”
