A man has died and three others were seriously injured following a fight outside a 21st birthday party at a football ground.

Police said the incident happened around 12.35am on Sunday at Shettleston Juniors Football Ground in the east end of Glasgow.

Four men were found injured at the scene at Shettleston Road before they were taken to Glasgow Royal Infirmary.

One of the casualties, aged 24, died a short time after arriving at hospital. Police are treating his death as suspicious.

The other men - aged 23, 25 and 26 years old - were treated for serious injuries but have since discharged themselves from hospital.

Police said a 21st birthday party had been held at the club on the night in question and have asked for people who attended it to help with enquiries.

Detective Inspector Martin Fergus said: "We are currently viewing CCTV and carrying out door to door inquiries in order to establish the circumstances surrounding this incident.

"We know that there had been a 21st birthday party function at the club and I would appeal to anybody who was at the function, or knew of anybody attending the function, to please contact us.

"It is clear that this disturbance took place in the street, therefore if you saw or heard anything, no matter how trivial you may think it is, it is vital that we speak to you.

"I also urge anyone who was passing by the football ground at around 12.30am this morning and saw anything suspicious to contact police immediately."
