Los Angeles County officials are offering a $25,000 reward after stray dogswere attacked and severely burned with a chemical agent in the Antelope Valley.
The Board of Supervisors approved the award on Tuesday for information leading to an arrest.
Sheriff's detectives are investigating at least seven incidents of dogs being burned between July 20 and Aug. 20 in and around Lancaster.
Investigators want to know if the attacks on a golden retriever and six pit bulls were related, what chemical or material was used, and if there are any more victims.
Residents have raised about $20,000 to help with medical costs for the dogs.
People for the Ethical Treatment of Animals previously offered a $2,500 reward for the arrest of the person responsible.
