Two men from Eccles, Salford, have been arrested on suspicion of attempted murder after a man was repeatedly stabbed at a Blackpool festival.
The 20-year-old and 26-year-old are still being held in police custody for questioning after the attack on Saturday 26 September.
That day, 2,000 people descended on Blackpool pier for the closing party of the Pier Jam electronic music festival.
At around 10.30pm a fight broke out on the North Pier in which a 23-year-old man from Manchester was stabbed multiple times.
He was taken to Royal Preston hospital and remains in a serious but stable condition.
Two other victims, a 30-year-old man from Bradford, and a 15-year-old boy from Manchester, were also stabbed in the attack. Their injuries are not considered to be life-threatening.
Lancashire Police recovered a knife from the scene and arrested the two Eccles men on suspicion of attempted murder and wounding.
Det Insp Gareth Willis of Blackpool CID said: “We are continuing our investigation into this extremely serious incident which could easily have cost at least one young man his life.
“I would like to take this opportunity to thank those witnesses who have already come forward to help us with our on-going enquiries.
“We are still keen to hear from anyone who witnessed the incident and has not yet spoken to us.
“If anyone has any information about what happened or has any information that could assist with our investigation then please do get in touch.”
