Mohammad Asim Raza (left) and Rana Haris Ali drowned
Waris Ali, from Glasgow, said he had taken off his shirt and tried to throw it into Loch Lomond so that his wife, Edina Olahova, could grab on to it but that she was unable to do so.
Ms Olahova, 29, and son Rana Haris Ali, died in the incident along with Muhammad Asim Riaz, 41, the family friend, on Saturday evening.
The incident unfolded after Mr Riaz’s seven-year-old son fell into the water after playing at the end of a pier. The adults and the other child went into the water, which Mr Ali said appeared shallow and safe, in a bid to rescue him but soon got into difficulties.
