A dad whose daughter died in a speedboat accident on the Thames in 2015 has been fighting to get answers ever since.

Charlotte Brown, known as Charli, died on December 9, 2015 at the age of 24 after she and her 29-year-old date were thrown into the river near Wandsworth Bridge.

The police at the time deemed the death as non-suspicious but today are investigating whether there could be a basis for a manslaughter charge or other criminal offence.

The “fun-loving” woman from Welling had met her date on an online app and after dining at the Shard, she went with her date on a speedboat trip on the Thames.

Emergency services recovered the pair from the water but, while her date survived, Charli was pronounced dead at 1.55am later that night.

Her dad Graham Brown feels there are a number of unanswered questions that could prevent a similar tragedy from befalling others.

Mr Brown, who works for the Ministry of Justice as a prison population manager, said: “Even though my daughter died in 2015 we still don’t have an inquest date.

“The circumstances of the incident are such that an investigation is still ongoing and the inquest is yet to be heard.

“She died in the most tragic circumstances. It was 10pm on a full tide and they were wearing no lifejackets. That could have killed any other woman who was with them.”

Mr Brown has since become heavily involved in fundraising activity for the Royal National Lifeboat Institution (RNLI).

He raised £2,500 running the Great Northern Run and now plans to raise money running the London Marathon, setting up a JustGiving page with a goal for a further £2,500.

A spokesperson from Met Police said: “The police investigation into the death of Charlotte Brown remains ongoing and the Metropolitan Police Service (MPS) continue to liaise with Charlotte's family as to developments.

“Following the submission of a file to the Crown Prosecution Service advice was provided to the MPS and detectives are now investigating offences including manslaughter.

“Due to the nature of the offences being looked at, Detectives from the Homicide and Major Crime Command are now investigating.

“They continue to liaise with colleagues from the Port of London Authority and the Marine Accident Investigation Branch.

“An inquest was due to commence on 5 October 2016 at Westminster Coroner's Court but this has been rescheduled on a date yet to be confirmed.”
