A second teenager was arrested in connection with the death of a man in the town centre.
Piotr Ludwiczak, 35, died after an incident outside a bar on Silver Street last weekend.
Today, police said a 19-year-old man was arrested on suspicion of violent disorder. He was released under investigation.
Previously, police said another 19-year-old man, Brook Marshall-Byrne, of Prestwich Hills, was arrested on suspicion of affray and manslaughter. He was charged and he appeared Manchester Magistrates' Court earlier this week.
In a statement, a spokesperson for Piotr's family said: "Piotr, also known as Peter, was loved by his family and friends.
"He had a giant personality and loved making people laugh, he certainly made his partner and young son smile every day.
"Piotr was well-liked by everyone he met, both in the UK and Poland.
"He was a gentleman, always keen to lend a hand to anyone who needed help.
"Piotr worked hard to provide for his family and was never happier than when he was spending time with them. He was loved by many and there are no words to describe the pain that is now being experienced by all that knew him.
"It is difficult to comprehend that Piotr has died under such tragic and needless circumstances and it is heartbreaking to know he will never walk through the door and hug his son again.
"The family are devastated beyond belief and find it hard to imagine life without him."
A spokesman for Greater Manchester Police said: "Piotr’s family have been kept updated with the progress of this investigation and continue to be supported by officers.
"The MIPP Portal remains open and any further witnesses are still sought.
"Any information including CCTV, mobile phone or Dashcam footage can be provided to police via this portal - Public Portal (mipp.police.uk)
"They can contact Crimestoppers on 0800 555 111."
