Delaware State Police said a 38-year-old man was taken into custody after surrendering to police following a stand-off Tuesday.
Authorities had evacuated residents from a neighborhood south of Dover as they dealt with a barricaded man, authorities announced Tuesday.
According to police, officers were dispatched to a home in the unit block of Howe Drive in Highland Acres around 9:10 a.m. on June 25, 2019, to check on the welfare of an "unstable male subject alone in the house."
That individual was identified by authorities as Justin Topolski, and the concerned call came from his mother, who reported her son had threatened her with a knife during an argument inside their residence.
Police said Topolski entered the residence when police arrive, refused to exit, and fired shots in the direction of responding troopers. He struck a marked Delaware State Police SUV parked in the driveway during this time, police said.
Howe Road was closed and several residences in the area were evacuated, police said. The Special Operation Response Team and Conflict Management Team both responded to assist with making contact with the individual, police said just after noon on Tuesday.
Topolski exited the residence around 1 p.m. and was taken into custody without further incident. He was transported to an area hospital for evaluation.
There were no reported injuries as a result of this incident, police said.
An investigation remained ongoing, and police said charges may be possible following the conclusion of the investigation.
