A teenager died while swimming with dolphins just two days after being best man at his dad's wedding in Mauritius.
Callum Howkins, 17, from Hinckley, died in the tragic accident on 29 August.
He was taken by boat 500 yards from the reef in Tamarin Bay. Fellow swimmers raised the alarm when Callum failed to surface.
His body was found an hour later by the National Coastguard and taken to Yves Cantin Regional Hospital in Black River.
The skipper of the boat that took him to the spot where he died has now been "provisionally" charged with involuntary homicide.
Police spokesman Darmarajen Mooroogan confirmed that an arrest has been made.
According to the Mirror, he said: "Callum was on an excursion off the coast of Tamarin Bay when he drowned while swimming.
"A skipper of the boat that conveyed him has been arrested. A preliminary charge of involuntary homicide by imprudence was lodged against him before a court of law. He did appear in court and was released on bail."
"The investigation is at a very early stage and we are not yet prepared to discuss details of the accident."
He dismissed reports that Callum had been dragged into the depths of the ocean by a dolphin.
"Gentleman" Callum had been working at a pub part time while waiting to start an apprenticeship with Caterpillar.
His mum Louse told the Birmingham Mail: "I can't put into words how amazing he was. He was beautiful inside and out.
"He was always so happy. He loved to take selfies and always looked smart. He had a big group of friends – both girls and boys – and he was loved by everyone. We are a very close family and he loved being a part of that.
"He always studied hard and he always enjoyed school."
His dad Gavin said: "He was a real gentleman and treated everyone with so much respect. He touched everybody's lives."
