A Polish man has died after diving into Lake Garda in Italy – marking the sixth fatality there this month.

The 42-year-old went into the water at Desenzanino beach but failed to surface, causing his friend to alert the coastguard.

The body of the man, who has not yet been named, was found two metres (6.5ft) deep by fire brigade divers, Italian media reported.

His death comes as the search for Briton Aran Chada, who disappeared under the water after saving his teenage son, continues to take place.

The 51-year-old sales director, from the Leicestershire village of Woodhouse Eaves, hired a boat with his two children and wife on the lake near Limone on Friday.

They were about 500m (0.3 miles) from the shore when Mr Chada’s 14-year-old son got into trouble in the water

Mr Chada dived in and managed to save him but then got into trouble and slipped beneath the surface.

He has not been seen since and is it feared he may have drowned.

A spokesman for the coastguard said: “The man dived to save his eldest son who was in trouble and managed to push him back to the boat but then he got into trouble.

“It was very hot on Friday afternoon, but the water was 10 degrees colder, so it’s possible he had a seizure from the shock.”

Over the past week, Lake Garda has seen temperatures reach 31C or higher.

Like Mr Chada, there is still no trace of 33-year-old Pakistani man Hasnain Zeb, who jumped off a pedal boat into the lake at the end of June, according to Italian media reports.

On Sunday, 41-year-old Alessandro Redaell, who was originally from Lecco in northern Italy, was also found lifeless after diving into the water from a boat.
