A man has been arrested on suspicion of murder after a 19-year-old was killed in a machete attack outside a pub in Gloucester.

Police said the murder weapon, which has yet to be traced, is thought to have a blade of at least 2ft in length.

The victim, named locally and on social media as Zac Evans, was pronounced dead after he and two men were attacked outside the Pike and Musket pub at about 12.40am on Saturday.

In a Facebook tribute, Sylv Evans said her son was a "wonderful son, brother, grandson, boyfriend and friend".

She added: "Rest in peace Zac. Words cannot describe how heartbroken we are. You will be greatly missed."

A 22-year-old man was left with serious injuries after the attack, and is now in a stable condition following surgery at the Gloucestershire Royal Hospital.

A third man, aged 18, sustained minor injuries in the fight, which unfolded on Windsor Drive in Tuffley.

Detective Chief Inspector Steve Porter said officers were still attempting to establish a motive for the violence.

He added: "During the investigations that followed a local man was arrested on suspicion of murder at 2.30pm this afternoon.

"We are also keen to trace what we believe to be the weapon in this attack, which is a large machete-type weapon with a large blade at least 24 inches long.

"If anybody knows the location of that weapon, or where it could be discarded, we would ask them to come forward."
