FBI arrests suspect accused of shooting at LA police

James Brook, 19, who with an accomplice, allegedly opened fire on LA police officers in their patrol car.

LOS ANGELES - A second suspect has been arrested for allegedly opening fire on two Los Angeles police, the FBI said Thursday, with the United States still on edge over the murders of two New York officers.

The alleged shooter, James Brooks, 19, was arrested Wednesady in Las Vegas, the FBI said in a statement.

Authorities launched a manhunt for Brooks, who, with an accomplice, allegedly opened fire on the LA police officers in their patrol car Sunday, said officials, who added that no one was injured.

The other suspect was detained shortly after the incident, authorities said.

Law enforcement across the United States has been on alert after the fatal shootings of the two officers in New York earlier this month.

America's largest city was left in shock by the killings of Wenjian Liu, 32, and Rafael Ramos, 40, shot in the head as they sat in their patrol car in broad daylight in Brooklyn on December 20.

The two officers were slain following nationwide demonstrations over the killing of several black suspects by police, amid historically bad relations between US law enforcement and the African American community.
