Washington DC police arrest man accused of mansion murder

Police have arrested a man they believe held hostage and tortured a family and housekeeper in their Washington DC home before killing them.

Daron Dylon Wint, 34, who had previously worked for the victims' family business, was detained late Thursday in the US capital.

He is accused of killing the four victims and setting the house on fire.

Savvas Savopoulos, 46, chief executive of American Iron Works, was found dead in his family's home in Woodley Park, northwest Washington, just blocks away from the home of Vice-President Joe Biden.
