A 17-year-old youth was killed allegedly transporting a bomb that exploded in the Shia village of Bani Jamra, Bahraini police said Wednesday.
A caller had reported Tuesday's explosion and discovery of a body in a deserted area, a police spokesman said in a government statement.
"Initial investigations revealed that the bomb had exploded while the person was carrying it to plant it at another location," he said, adding that the youth was "wanted on criminal charges."
"A bomb, a gun and ammunition were found near the body," he said. "The collection of evidence is still ongoing."
A Shia-led uprising to demand a constitutional monarchy was crushed in March 2011, but several homemade bomb attacks have since been carried out across the Sunni-ruled kingdom.
Bahraini Shias continue to demonstrate in villages outside the capital and frequently clash with police.
At least 89 people have been killed since the protests began, according to the International Federation for Human Rights.
