MONKEY ISLAND, Oklahoma - Two men were stabbed and a third set himself on fire on Monkey Island Thursday, according to a Joplin TV station.

KOAM TV reports two men ran into the Landings On Monkey Island Market & Grill asking people to call police.

Both had stab wounds, and a witness who works at the post office said he helped with first aid.

Someone else came into the convenience store and said a man outside had doused himself with gasoline and set himself on fire. KOAM reports that man is a suspect in the stabbings and was taken into custody but then sent to the hospital for burns. 

The Oklahoma State Bureau of Investigation said the three men were transported to various hospitals in unknown conditions. No names have been released at this time.

OSBI said all three men worked for Land Care, a lawn service based in Tulsa.

Agents said it appears the men pulled to the side of Highway 125 to eat lunch when the altercation started.

The investigation is ongoing.
