Westfield Street in St Helens town centre has re-opened after it was closed following the murder of bouncer Danny Fox.
The road, one of the most popular areas in the borough’s nightime economy, was shut to allow officers to complete forensic examinations of the murder scene.
Mr Fox, 29, was killed after he was chased from the scene of an argument by a man wielding a knife.
He was pronounced dead after being rushed to Whiston Hospital.
The off-duty bouncer had been stabbed in the collarbone.
