Authorities from multiple agencies were engaged in an over 15-hour standoff with a barricaded gunman this weekend. Port Huron Police responded to the 1100 block of Chestnut Street on reports of shots fired around 5:30pm Saturday. The standoff began when police attempted to make contact with the 23-year-old man who had barred himself inside his home. All family members, with the exception of a 16-year-old who stayed inside, managed to flee the house before police arrived. After being detained against their will, the youth was eventually able to escape. Nearby residents were ordered to shelter in place and several more shots were fired by the suspect from the home throughout the night. The suspect was spotted wearing body armor and had access to several firearms, according to authorities. Shots were fired at a tactical drone and at a Michigan State Police armored vehicle, causing minor damage. With the use of gas irritants, police were able to enter the home and take the suspect into custody just before 9am Sunday morning. The shelter in place order was soon lifted, however a strong police presence around the suspect’s home lasted until late in the day. Authorities have not yet released the name of the suspect or the circumstances that led to the incident.
