Three police officers were killed and two were injured in a shooting in York County, Pennsylvania, on Wednesday afternoon, Pennsylvania State Police Colonel Christopher L. Paris said in a news conference.

The two injured officers are in critical but stable condition at the hospital, Paris said.

The gunman is believed to have died of a self-inflicted gunshot wound, the sources said.

The incident happened just after 2 p.m. near the 1800 block of Haar Road in North Codorus Township, south of York.

WellSpan Hospital in York is on lockdown, CBS 21 in Harrisburg reports. The York County coroner also confirmed to CBS 21 that they were called to the scene of the incident.

The hospital confirmed it is treating two people who are “in serious condition” related to the incident and said “enhanced security protocols” are in place at the facility.

Pennsylvania Lt. Gov. Austin Davis on social media asked people to “please send prayers to the officers and those involved in the shooting in York County” and urged people to follow guidance from law enforcement.

Pennsylvania Attorney General Dave Sunday said he is on his way to the area as well.

U.S. Attorney General Pam Bondi said on social media that the FBI and ATF are on the scene to support local law enforcement. “Violence against law enforcement is a scourge on our society and never acceptable. Pray for the officers involved,” Bondi said in the post.

Department of Homeland Security Secretary Kristi Noem confirmed her department is also monitoring the situation and “working with interagency partners.”

Northern York Regional Police Department and York County sheriffs office are leading the investigation.

Schools in the Spring Grove Area School District sheltered in place because of the incident, but have since gotten the “all clear” from law enforcement, according to the district website. The move was made out of an abundance of caution, and no students or schools were involved, the message online says.
The response to the officers’ injuries unfolded on a rural road that winds through an agricultural area not far from the Maryland state line.
