A famous sculpture by Barbara Hepworth has been stolen by suspected scrap metal thieves from a park in south London.

The large bronze sculpture, called Two Forms - Divided Circle, had been on public display in Dulwich Park for more than 40 years.

Angela Conner, a sculptor and former assistant of Barbara Hepworth expressed sadness at the theft.

But she said it was possible a mould of the sculpture may exist, in which case, it could be re-cast.
