Schools went on lockdown Monday as police searched for a man suspected of attempting to kill a local police officer on Sunday night in Manchester Township, a northern suburb of York, Pennsylvania.

On Monday, Central York School District kept students indoors and closed buildings to outsiders as police searched the area for 24-year-old Trev Bowies Jackson.

“Police have advised it is safe for students, faculty and staff to conduct school as normal within each of these buildings, and to move freely within the schools,” a Central School District alert said, according to the York Daily Record.

Police were searching for Jackson as a suspect in an attack on Northern York County Regional Officer Lynn Anderson who was attacked after a routine traffic stop.

Northern York County Regional Police said that Anderson stopped Jackson in Manchester Township after his car was seen swerving on the road.

Police report that officer Anderson smelled marijuana in the car and ordered Jackson to exit the vehicle, but as the officer began to try to arrest the man, Jackson pulled a gun and fired three rounds at the officer.

Officer Anderson fell the the ground, rolled, and fired six shots of his own at Jackson who hopped back into his car and sped off. Neither the officer nor the suspect appear to have been wounded in the gunfight.

But as Jackson sped off, police say he nearly hit several other officers responding to the scene.

Northern Regional Police Chief Mark Bentzel told the media that, once apprehended, Jackson will be charged with criminal attempt of homicide, aggravated assault, and reckless endangerment of another person.

Those with information on Jackson or his whereabouts should contact the Northern York County Regional Police Department at (717) 292-3647, call 911, or use the crime tip page on the Northern Regional website.

Pennsylvania Crime Stoppers is also offering a cash reward for help in Jackson’s apprehension. Anyone with information should call the Crime Stoppers at 1-800-472-8477.
