Shocking video shows three-year-old girl's final moments as she is thrown in a hotel pool by her stepfather before drowning.

A shocking video has emerged which shows the horrific final moments of a three-year-old girl after she was thrown into a hotel pool by a man, believed to be her stepfather, and drowned. Watch video below :

The well-built man, who has not been named, can be seen repeatedly throwing the little girl into the swimming pool in Morelia, in the south-west Mexican state of Michoacan. 

She is seen battling to keep herself afloat in the footage, which was captured on the hotel's CCTV cameras on August 12 and posted online by Quadratin News.

The man is filmed forcefully tossing her into the water and submerging her several times, while other guests are in the pool.

At one point he throws her in and walks away before returning and tossing her back in when she is fully-clothed. 

 The mother is said to have taken her daughter to hospital after realising she wasn't breathing and doctors confirmed she had died.

A post-mortem examination is said to have revealed that the cause of death was mechanical asphyxia by drowning.

Police say a man, believed to be the toddler's stepfather, has been arrested and charged with homicide and treason.

He has been detained in custody while investigations, which could take months, continue.
