SAO PAULO - Animal rights activists and police have been clashing in front of a laboratory in Brazil that used dogs for drug tests.
The confrontation came a day after activists broke into the lab and released 178 beagles being used to test for adverse effects of drugs manufactured by the pharmaceutical industry.
Local police say about 500 activists, including members of an anarchist group, Saturday tried to break through barriers set up in front of the lab, threw rocks and set fire to a police car and media vehicles. Police responded with tear gas and pepper spray. There's no word on arrests or injuries.
