LONDON, Ont. — Two more teenagers face charges after police say a masked trio robbed a pizza joint with a samurai sword and a hunting knife last week.

The night of Feb. 14, the teen suspects threatened staff before making off with cash, police said.

The accused, ages 14, 15 and 17, can't be named because they're minors.

The 17-year-old, from London, was arrested hours after the robbery.

All three face robbery charges, and two of them are also charged with uttering death threats and possession of a dangerous weapon.
