The family of Zac Evans have paid tribute to him as a "happy chap" who "constantly gave us endless laughter, fun and immense pride."
He was a happy chap and from the start we knew he would make something of his life. Even at a young age he knew exactly what he wanted and made it happen.
As he grew older, Zac and his twin brother Nathan were the best of friends and constantly gave us endless laughter, fun and immense pride. Zac was always very creative and took immense pride in taking things apart and putting them back together.
Zac would always go out of his was way to make someone feel happy. He was very proud and close to his family, friends and girlfriend Beth, and would step in to help anyone if they were in trouble. He was one of the bravest, kindest young people, I have ever had the privilege to meet. The fact he was our son, was an added bonus. Zac was a truly wonderful son, grandson, boyfriend and friend.
Police in Gloucester have held a press conference this evening confirming that they have arrested a man on suspicion of murder after an alleged machete attack outside a pub. 19 year old Zac Evans died in the attack, which also left two others injured.

A fatal attack outside a Gloucester pub in the early hours of this morning was premeditated, locals are telling me.
There is no word on any arrest yet or recovery of the weapon - thought to be a machete - thus far.
Therefore the killer is "still at large", to use the words of one person at the scene in Tuffley.
The few people who have turned up here with flowers so far have been young - perhaps a reflection of the young age of the victim.
One man has died and another left with serious injuries after a suspected machete attack outside a pub in Gloucester, police say.
A murder investigation is now underway after a 19-year-old local man was pronounced dead at the scene of the fight outside the Pike and Musket pub in Tuffley.
The second man, 22, is now in a stable condition following surgery.
A third, 18-year-old man sustained minor injuries.
Gloucestershire Police say they would like to speak to anyone who witnessed what happened in the pub's car park or was in the area at the time.
Police are hunting a convicted burglar who has absconded from HMP Leyhill - the third inmate to go on the run from the prison inside a week.
Avon and Somerset Police said Michael Dare - described as a risk to the public - was last seen at the prison in South Gloucestershire at around 5pm on Friday.
The 29-year-old, who is serving a 20-month sentence for a burglary committed in 2010, has links to Suffolk but is believed to be in Birmingham.
He is described as white, 5ft 11ins, of heavy build, with an angular face and receding brown hair.
A Prison Service spokesman said it had "tightened the eligibility for open prisons following a comprehensive review".
