JAKARTA, July 5 (Xinhua) -- Three bombs exploded in a house in Pasuruan district of East Java province on Thursday, wounding a child and the alleged owner of the bombs, provincial police spokesman Senior Commissioner Frans Barung Mangera said.
The first bomb exploded at about 11:30 a.m. local time in a house at Pogar village of Bangil sub-district; in a matter of minutes, the second bomb went off, followed by the third one, the spokesman was quoted by Metro TV as saying.
The police are pursuing a man named Anwar suspected to be the owner of the bombs and he has escaped, Mangera said.
A woman, wife of Anwar, was detained by police, he added.
The blasts injured a 6-year-old boy, the only child of the alleged owner, and himself, an eye witness living near the scene, said.
"When I was coming into the house soon after the blast, I saw the kid with face turning to dark and covered with blood with a hole in one of his eyes," the witness said.
The alleged owner with blood on some parts of his body fled, the witness revealed.
Just after leaving the house, the man threw bombs to the police chief of Bangil sub-district who had just arrived at the scene, the witness said.
Police seized evidence, including nails and a book on how to engage in a holy war or Jihad, the television reported.
