Protests erupted at a South Los Angeles intersection Sunday night not far from where a teenager died in an officer-involved shooting after police say he fled from a suspected stolen vehicle.

Shortly before 10 PM, authorities have issued a citywide tactical alert and asked protesters standing at the intersection of Western Avenue and 108th Street to disperse else they would be arrested. After the evening at least four people had been taken into custody. The alert had been called off around midnight.

Around 8 PM, more than two dozen people gathered together at the intersection of Western Avenue and 108th Street, prompting road closures and a heavier police presence.

Some of the protesters had been seen dancing on top of cars, while others drove cars into the middle of the intersection and did multiple donuts before speeding away.

The protests came a day after 18 years old Carnell Snell Jr had been killed by police behind a home in the 1700 block of 107th Street moments after he fled from a suspected stolen vehicle that was involved in a car chase.

Police officers moved in to the front of the residence where people held a vigil for Snell around 5 PM. Officers said that the vigil was peaceful and "outside agitators" came to the area and were disruptive.

Eyewitness News got a look at the crime scene, where Snell died. Six shots riddled the side of the home and a seventh went through a window. A witness said that Snell died on steps in the backyard.

Police said on Saturday they found a handgun at the scene, but did not release further details on the shooting.

Activists had been asking for a transparent and quick investigation, and they wanted the officers who fired their weapons to be named.

Meantime, the president of L.A.'s Urban Policy Roundtable has met with Snell's family and may call for a Justice Department civil rights probe into the shooting.
