Zapped man ignites

A 50,000 volt burst from a police Taser gun set an American man on fire when the jolt ignited a butane cigarette lighter in his shirt pocket.

Florida's Sun Sentinel newspaper said officers zapped the man when he refused to drop a knife then threw him to the ground and rolled him around till the flames went out.

The 53-year-old man was treated for minor burns and two self-inflicted stab wounds.
