(CNN) -- A week after two New York City officers were killed while sitting in their patrol car, more police across the country are getting shot at.

In Los Angeles, two officers were driving in their patrol car Sunday night when at least one gunman open fire, police said. The officers returned fire and were not injured.

One suspect was arrested, and police recovered two weapons -- including a rifle.

But a second suspect remains at large, prompting an hours-long manhunt involving about 100 officers, Los Angeles police Capt. Lillian Carranza said.

Police warned residents to stay indoors part of South Central Los Angeles.

And in Pasco County, Florida, someone fired three bullets toward two sheriff's deputies as they were sitting in their cars Sunday morning, the Pasco County Sheriff's Office said.

"Both deputies reported hearing the whizzing sound of each projectile as they flew by," the sheriff's office said. "Deputies did not see the suspect or the vehicle from which the shots were fired."

Crime Stoppers of Tampa Bay is offering a $3,000 reward for information leading to the arrest of whoever fired at the deputies.

But the threats against local authorities didn't stop there.

The Pasco County Sheriff's Office is also searching for whoever spray-painted graffiti reading, "Shoot MP Cop." The graffiti was written on a road barrier in a subdivision called Meadow Point.

The latest shots fired at police come after New York police Officers Rafael Ramos and Wenjian Liu were gunned down in their patrol car on December 20.

The gunman, Ismaaiyl Brinsley, shot himself at a subway shortly afterward. Earlier, he had posted angry messages on social media against police and government, citing two black men killed by officers.

On Saturday, more than 25,000 police officers from across the country and even Canada attended Ramos' funeral.

Liu's funeral will be January 4.
