They are "so excited" to be joining the cast of the BBC medical drama in the role of Sah Brockner, the latest recruit to join the paramedic team alongside Jan (Di Botcher), Teddy (Milo Clarke) and Iain (Michael Stevenson).

Arin said: "I am honoured to be joining the spectacular 'Casualty' family as a shiny new paramedic!

"I’m so excited to portray this transgender, non-binary, salty but fiercely compassionate character and hope they are not only well-received, but also a source of awareness for those who have never met someone like me.

"I can’t wait for you to meet Sah!"

They are a cool character who doesn't want to be seen trying too hard, but they soon meet their match when working with boss Jan, who suspects a big heart is hiding somewhere inside their cold exterior.

Deborah Sathe, Senior Executive Producer of 'Casualty' and 'Holby City', said: "We are delighted to welcome Arin to the 'Casualty' family and launch our new paramedic Sah for the Saturday night audience.

"Sah will get themselves into all sorts of professional adventures whilst masking their own personal sorrow.

"In a world where our privacy is something to be treasured, will Sah be able to keep theirs?"

Arin will first appear as Sah on screen later this month.

'Casualty' is Arin’s first television role, after they graduated from Rose Bruford last year.

A delighted Arin wrote on Twitter: "I am so behind on Twitter sharing, but here is video evidence that I'm about to be on the telly"
