TURLOCK -- Three teenagers were arrested after a two-liter bottle filled with combustible ingredients exploded near a house, injuring the homeowner, police said.
The man suffered minor injuries Sunday and declined medical treatment for his abrasions, according to Sgt. Nino Amirfar of the Turlock Police Department.
The suspects, two 17-year-olds and a 16-year-old, face felony charges of possession of a destructive device in a public place. They were taken to Stanislaus County Juvenile Detention Center.
Police were called by the victim to the 800 block of Cedar Ridge Drive just east of California State University, Stanislaus, about 4:25 p.m. He said he had been injured from a plastic bottle that had exploded.

Police found five of the devices near the home.
It's unclear, but the man may have heard a knock on the door, and when he opened it one of the devices went off, Amirfar said.
Amirfar said he didn't know the ingredients inside the bottle. He said the bottles may have contained a couple of household products that, when mixed, build up pressure inside the bottle until it explodes.
The Stanislaus County Sheriff's Department bomb squad was called as well as the Turlock Fire Department. At least two of the bottles were detonated in the street.
The investigation led police to the three teens, one of whom lives in the area.
Amirfar said he didn't know of a motive, but said it appeared to be a random act.
In police training, he said, he's seen such devices knock mailboxes off of posts.
"They can kill you," he said. "Why you would put it in front of somebody's house ... it's beyond mischievous activities."
