Mumbai: A 29-year-old Syrian bodybuilder, who was in the city to participate in the Mr Universe World Championship, died of a suspected cardiac arrest, officials said on Saturday.

Mahmoud Ibrahim Alhdidi, who died last night, was set to participate in the 75kg weight category and was on a weight-control regimen ahead of the event which is to be held here on Sunday.

His body seemed to have lost a lot of salt which affected him fatally.

"He fell unconscious yesterday due to dehydration and was rushed to a hospital in suburban Malad by the organisers where he was declared dead for suspected heart attack," Indian Bodybuilding and Fitness Federation Secretary Sanjay More told reporters.

The tournament organisers have informed the Syrian Embassy officials about his death. His medical details are awaited.
