One police officer was killed and another was wounded after a gunman opened fire on them in San Diego on Thursday night, prompting a complete lockdown in California, Los Angeles Times reported. The police have taken a suspect into custody, and investigators asked residents to take shelter as they looked for another suspect.

The officers were shot at during a traffic stop in the city's Southcrest locality. They were taken to Scripps Mercy Hospital, where one of the policemen who had sustained multiple gunshot wounds died, according to police chief Shelly Zimmerman. The motive behind the shooting, which took place around 11 pm (local time) in the southern part of the city, is not known yet.

On July 8, five police officers were shot dead in Dallas after a protest rally against the killing of two African American men in the hands of the police in Minnesota and Louisiana turned violent. Only a fortnight after the incident, three policemen were killed and three others were wounded in Baton Rouge, Louisiana, after a resident from Missouri opened fire on them.
