A foreigner was seriously wounded when a device he was suspected of carrying exploded in the Thai capital Bangkok on Tuesday, police said.
Police investigators rushed to the scene after three men were seen fleeing from a house where a blast was reported in the east of the city.
One of the men hurled an explosive device at a taxi which refused to stop and later tried to throw another device at police, triggering a blast which tore off his legs, authorities said.
The suspect was admitted to a Bangkok hospital where he was receiving emergency treatment.
Thai police later charged a Lebanese suspect after they raided a property and discovered chemicals that could be used to make a bomb.
