Thahn Phan’s relatives are mourning after the 51-year-old was injured at the corner of Murray and King Street, leading to a brain bleed.

Police claim 24-year-old Alicia Kemp was steering the e-scooter, hopping on with a friend who’d been kicked out of a pub.

“A really unfortunate and sad set of circumstances,” WA Police acting assistant commissioner Darren Seivwright said on 6PR.

The UK tourist is alleged to have reached speeds of up to 25km/h, a speed described as “inexplicably dangerous” by a prosecutor.

They also allege she’d been drinking for six hours and had a blood alcohol reading of 0.158 when Phan was struck.

“On Saturday night, Thanh Phan – a cherished husband, father of two, brother, and dear friend – was hit by an electric scooter and critically harmed,” the family shared in a statement.

“Yesterday evening, we received the heartbreaking news that Thanh passed away as a result of his injuries.”

Kemp was charged with dangerous driving causing death.

The Phan family have lived in WA for more than 10 years, where the father worked as a structural engineer.

Neighbours described him as “unwaveringly positive, hard working, and one of the kindest people we have known”.

This evening, the family urged a “review of the governance and safety policies regarding rented e-scooters to help avert additional severe incidents that endanger lives”.

“We have very strict regulations about speed and power of e-scooters,” Transport Minister Rita Saffioti said.

“It’s obvious that we need to do more on compliance.”

Kemp cried as she was denied bail today, deemed too much of a flight risk.

Tomorrow is her 25th birthday, which she’ll now spend behind bars before facing court again next month.
