A 17-YEAR-OLD from Warrington has been arrested after a stabbing near Sherdley Park in St Helens.

The attack happened on Marshalls Cross Road shortly after 7.30pm yesterday, Tuesday, as thousands were gathering for the annual Spark in the Park fireworks display.

He was knifed in the back on a grass verge as families – many with young children – walked to the event.

Passers-by rushed to his aid and he was treated by paramedics. The injuries are not life-threatening.

Witnesses were left shocked and sickened.

“A 17-year-old male was treated by ambulance staff and has since been taken to hospital where his condition is described as serious but non life threatening.”

Superintendent Paddy Kelly said: "Although this incident did not happen at the fireworks display, this is a shocking incident which although is believed to be targeted, has taken place in an area where there are undoubtedly lots of innocent children and members of the public wondering around.

"This is currently a live investigation and officers at the scene are working with security staff to secure the area, analyse CCTV and conduct forensic analysis and urge anyone with information to come forward quoting log 1051 of 5th November."
