Many people living in Addison, Illinois, were asked to shelter in place for several hours on Thursday, and local schools took extra security precautions, after a man barricaded himself inside a home and fired shots at police.

Police said, shortly before 11 a.m., a 911 call came in from a man in the 200 block of East La Porte Avenue, telling dispatchers he needed police to find his dogs, and claiming if officers didn't come out, he would find someone to do the officers' job for them. The man then hung up, and dispatchers tried to call back, but could not reach him.

While officers were headed to the scene, other calls came in saying a man holding a bag was blocking the street with a white SUV, spraying an unknown substance on the street, and setting items on fire.

Shortly after 11 a.m., as officers arrived on the scene, they saw the man go inside a house. A short time later, the man started firing shots at police, shooting one officer in their protective vest. That officer was taken to the hospital, but has since been released.

Officers took cover and called in additional support from neighboring departments, the Northern Illinois Police Alarm System SWAT team, and the DuPage County Metropolitan Emergency Response & Investigations Team Task Force. 

Police said the suspect sporadically fired several shots from the home over the course of four hours before surrendering around 3:15 p.m., when he was taken into custody of the front lawn of his home.

No civilians were injured, but police said some police officers were taken to the hospital for minor injuries. 

Charges against the gunman were pending Thursday evening.

Police asked neighbors to shelter in place and stay away from the area during the standoff. Police said people should continue to avoid the area Thursday evening as investigators process the crime scene. 

Addison Trail High School was placed on a "secure" environment during the standoff, school officials confirmed. Dismissal will take place as normal, with the exception of route 39. School officials said students on route 39 should either be picked up by a parent, or wait until the school is cleared to dismiss their school bus to that area. Parents and guardians of students who walk to and from school are asked to pick up their child at school, and avoid the area near the 200 Block of East La Porte Drive.

Addison School District 4 schools also were placed on a "secure" environment during the standoff, and were adjusting dismissal procedures at all nine schools. Car riders and bus riders will be dismissed as normal. Students who walk to school must be picked up by car. All after-school events and activities for Thursday have been canceled.
