Police in Jamaica are holding a man in connection with the killing of former heavyweight champion Trevor Berbick.
Trevor Berbick was found on Saturday with gaping head wounds
Berbick, the last boxer to fight Muhammad Ali, was found in his native Norwich, north east of Kingston, with gaping head wounds.
Local police told the BBC a man had been arrested over the killing on Saturday in the Portland region of the island, but no-one had been charged.
Berbick beat Ali in 1981 and briefly held the WBC heavyweight title in 1986.
He was found at around 0500 local time (1000 GMT) by a church deacon at the Norwich Baptist Chapel near his home in Port Antonio, according to the Sunday Gleaner in Jamaica.
Senior Detective Sergeant Kenneth Bailey of the Port Antonio Criminal Investigation Branch, is quoted by the paper as saying: "He reportedly left one of the local night spots between the hours of 1.45 to 2am Saturday and headed for home.
"The body had four wounds to the back of the head, as he was probably attacked from behind.
"The impression and damage done to the skull have indicated that a machete may have been used by his attacker or attackers to murder him."
Police believe the attack was not a robbery because Berbick was found with cash and no attempt had been made to enter his house a few feet from where he was found.
Berbick was aged 51 or 52 - his birthdate was disputed.
When asked once about his age, a detail that was never nailed down during his lifetime, Berbick said: "Legally, I'm a spirit. I have no age."
