Story highlights LAPD: No indication shooting is linked to nationwide protests about police

Two Los Angeles police officers were shot at, but neither was injured

About 100 LAPD officers searched for a suspect in South Central LA

In Pasco County, Florida, two deputies were also shot at but not injured

(CNN) Two Los Angeles police officers were shot at Sunday night while they drove their patrol car in the southern part of the city, police said. The officers returned fire, authorities said, and no one was injured.

One suspect was arrested and two weapons, including a rifle, were recovered. Another remains at large, prompting a manhunt that lasted for hours and involved about 100 officers, LAPD Capt. Lillian Carranza said.

Police warned residents to stay indoors in part of South Central Los Angeles. On Monday, police reopened access to streets inside a six-block perimeter they set up overnight.

LAPD Detective Megan Aguilar told CNN that investigators have "nothing to indicate that there's a nexus" between the shooting and recent nationwide protests against police brutality that have fueled animosity toward police.

And there was a second incident over the weekend in which police were fired at, this one in Florida on Sunday morning.
