A sale of items belonging to notorious US gangster Al Capone has raked in $3m (£2.2m) at an auction held over the weekend in Sacramento, California.

Some 174 items – including personal photographs and firearms as well as jewellery and furniture – featured.

The event, called A Century of Notoriety: The Estate of Al Capone, was held at a private club and attracted nearly 1,000 bidders.

The most popular item was Capone's favourite gun, which went for $860,000.

The gun is believed to have reached the highest selling price for a 20th-Century firearm sold at auction, according to the Chicago Tribune.

Al Capone was a Chicago mobster known as Public Enemy Number One for his relatively brief reign as crime boss in the 1920s during the Prohibition era. He was eventually imprisoned for tax evasion, and spent several years locked up in Alcatraz.

Diane Capone – one of of Al Capone's three surviving three granddaughters, who live in California – said the decision to sell the items was based on her and her sisters getting older, Reuters reports.

She also said the increasing threat of wildfires to their homes in northern California had been a factor.
