Detectives have arrested a 33-year-old man on suspicion of murder following an attack on Northampton Racecourse this morning.
Ambulance crews were called to a report of an injured man around 10.50am and they called the police when they arrived at the scene.
It became clear he had been stabbed and although police and paramedics fought to save him he died.
St Georges Avenue has been closed from Brick Kiln Lane to Trinity Avenue and the section of Racecourse alongside it has also been closed as far as the adventure play area in the centre.
Last night police sentries were guarding the clumps of trees in the centre of the park.
A police search team was moving through sections of the park fanned out scrutinising the ground step by step.
Senior Investigating Officer, Detective Inspector Pete Long, said: “We are still in the early stages of a very fast-paced investigation and a large team of Major Crime detectives are working on the case in order to bring the offender to justice.
“We have arrested a 33-year-old man but we are still keeping an open mind and would continue to appeal to anyone with any information to come forward.
“If you saw something suspicious in or around the area this morning or last night, please contact us, no matter how small or insignificant you think your information might be.
“Following some initial enquiries, I also want to reassure the public that we believe that this was an isolated incident and there is nothing to suggest any ongoing risk to members of the public.
“Increased patrols are taking place in the area to reassure the local community and house-to-house enquiries are also being conducted. If you have any concerns, please do not hesitate to approach an officer in the area.”
St George’s Avenue remains closed and motorists and pedestrians are still advised to avoid the area.
