Police have launched a manslaughter probe into the the death of a young woman who died in a speedboat accident while on a first date with a man she met online.
Charlotte Brown, 24, was found in the Thames after a boat carrying her and her date capsized near Wandsworth Bridge in December 2015.
Police at the time deemed her death as non-suspicious but this week confirmed they are investigating for foul play.
Miss Brown, who lived in East Finchley, North London, met her 29-year-old date on an online app.
After dining at the Shard in central London, the pair took the Thames for a speedboat trip without life-jackets.
But their boat capzised at around 11.45pm and emergency crews scrambled to the scene to search for them.
Miss Brown’s 29-year-old date was found clinging to the upturned boat and pulled from the water within minutes but Miss Brown was found unconscious after up to 20 minutes and later died in hospital.
