Osagi Bascome, 23, was stabbed multiple times during a scuffle outside a restaurant on St David’s Island.
Bascome signed for Bristol City in February 2017 as a teenager after impressing in a lawsuit in late 2016.
He played for the Under 23s for the remainder of this season.
Bascome ended his English football career in the National League north of Darlington.
He has been selected 18 times for Bermuda, often alongside current Bristol City striker Nakhi Wells, and has scored one goal.
Police said the stabbing was not linked to a gang.
Detective Inspector Peter Stableford addressed the press outside the “Zone” where the attack took place, urging witnesses to come forward.
“We need to hear from everyone who was at the party, but at the moment the people who were there are not talking to us,” he said.
“We know people saw what happened and we urge them to do the right thing by Osagi and tell us.”
A Bermuda police spokesperson said: “A police investigation has been opened into the circumstances surrounding the death of a 23-year-old man, who died of injuries sustained in an apparent stabbing incident. .
Officers were at King Edward Memorial Hospital in connection with another case, when they were alerted to the victim who had been brought to the emergency department in a state of unresponsiveness, with which seemed to be multiple stab wounds. ”
The victim was transported to hospital in a private vehicle. Details are limited at this time. ”
