Fast-fashion giant Shein has launched an investigation after an image of Luigi Mangione - accused of murdering UnitedHealthcare CEO Brian Thompson in New York last year - was used to model a shirt.

An image with his likeness, which appeared to show him wearing a white, short-sleeved shirt, appeared on the fast-fashion website until its removal.

It is thought the product Mr Mangione appeared to be modelling was on sale for just under $10 (£7.50).

A spokesperson from Shein told BBC News: "The image in question was removed immediately upon discovery."

"We have stringent standards for the content of listings on our platform", the spokesperson added.
