The Turlock Police Department put a pit bull into quarantine after it bit a young boy in an unprovoked incident.

The 11-year-old boy sustained a bite to his arm and was treated at a local hospital, Turlock Police Lt. Ron Reid said.

The 11-year-old was visiting a friend in an apartment in the 100 block of Starr Avenue early Saturday evening.

The boy had been in the apartment with the dog with no problems, but later as he was walking through the courtyard, the dog ran up and bit him, according to the police department.

The incident was reported to the police and the owners of the dog willingly gave him up to be placed in quarantine. California law regulates that a dog that has bitten someone be placed into a 10-day quarantine at an animal shelter to determine if the dog is vicious, rabid, or diseased. If the dog is found to be in good health, vaccinated and does not pose a public safety threat, it may be returned to the owner.
