THE body of a “hero” Brit dad who dived into a lake to save his son has been found more than three weeks after he vanished. Aran Chada, 51, leapt into the water in Italy’s Lake Garda after spotting his teenage lad in trouble swimming on July 22. Aran Chada was on holiday with his wife and two kids when he jumped into a lake to help his son LinkedinThe 51-year-old’s body has been found weeks after his disappeared[/caption] His family feared him dead as he failed to resurface after helping his son onto a boat. They believed oil executive Aran, from Leicestershire, had a seizure from the shock of the cold water before disappearing beneath the surface. The Italian Coastguard said his body was found on Tuesday, more than three weeks on “more or less in the area” where he was last seen following an extensive search using underwater drones. A Guardia Costiera spokesman said: “the drowning was probably caused by an illness following the rescue that Mr Chada had carried out on the first child, who was in danger.” More world news 'I DON'T LIKE HIM' Salman Rushdie suspect says author 'attacked Islam' as he speaks in jail AXIS OF EVIL China sends thousands of troops to RUSSIA for massive war games amid WW3 fears Aran was on holiday with his partner Holly Mosley, 39, and their two kids, aged 14 and seven, when tragedy struck.

After Aran disappeared, Holly’s visibly shaken brother James told The Sun: “It’s devastating. What my sister and the family is going through is unimaginable.” The coastguard, in comments first reported in The Times, previously said Mr Chada may have suffered a thermal shock seizure. Temperatures were around 38C but the water was “a good 10 degrees colder”. Speaking at the time, coastguard commander Antonello Ragadale told the paper: “This man was a hero and we fear he drowned, but we’re doing everything we can to find his body.” The Foreign Office said in a statement: “We are supporting the family of a British man who has died in North Italy and are in contact with the local authorities.” It comes after six people tragically drowned in Lake Garda within a month.
