The son of a wealthy art collector accused of trying to murder the live-in maid at his family's luxury £20million home is receiving treatment in a psychiatric unit, a court heard.

Maximillian Bourne, 25, is said to have repeatedly stabbed Joselia Pereira Do Nascimento at the five-bedroom property in Chelsea on February 25.
