Two people were arrested during protests in El Cajon in California on Thursday following the fatal shooting of a black man by a police officer. Authorities used pepper balls at the demonstrators who stopped vehicles, broke car windows and knocked a man off his motorcycle, the El Cajon Police Department said Thursday.

The protests spilled on to a third night after one officer opened fire and the other one used a stun gun on Alfred Olango Tuesday. Police had responded to calls complaining about an unstable man walking in traffic. 

On Thursday, police arrested two men — aged 19 and 28 — who are residents of El Cajon. Their identities were not released.

“Tonight, a group of between 50 and 75 protestors occupied the intersection of Broadway and Mollison in El Cajon. ... An unlawful assembly was declared by law enforcement [per section 407 of the California Penal Code] at the scene and notice was given to the protestors to disperse,” the police department said in a statement

Meanwhile, Olango’s family and friends — who said he was mentally ill —have urged authorities to release the full video of the shooting. The 38-year-old had come to the U.S. decades ago from Uganda as a refugee.

Olango had prior run-ins with the law. Authorities at the Immigration and Customs Enforcement office said that federal authorities tried twice to deport him However, Uganda refused to take him in.

Olango’s family is expected to hold a rally Saturday against his fatal shooting.

Authorities have launched an investigation into the shooting.
