A murder investigation has been launched after a man’s “violent and shocking” death.
Officers were called to reports of an assault at a bar on Bow Street, Ashton-under-Lyne at about 2:40 BST, Greater Manchester Police said.
The force said a man in his early 30s was found with serious injuries and died at the scene.
A 36-year-old man has been arrested on suspicion of murder and remains in custody for questioning, it said, adding it believes it was an isolated attack.
Det Supt Ian McNabb said: “This is was a violent and shocking attack that tragically took the life of a young man.”
He said detectives were working “at pace” to establish the full circumstances surrounding his death.
McNabb said while no formal identification has taken place yet, the family of the who they believe to be the victim have been told and were being supported by officers.
“We currently have a man in our custody and a scene is still in place at this time.”
He said: “We would also like to reassure the community we believe this to be an isolated attack and poses no wider threat to the public.
“As we are still in the early stages of our investigation, we are appealing for anyone who may have information to please come forward and report.”
He added: “This can be anyone who may have witnessed the incident itself, or has any footage from the area that may support our enquiries.”
