A "domestic incident" in Churchville Tuesday morning turned into a standoff with Harford County Sheriff's Office tactical unit deputies that lasted over four hours and caused a section of the busy Route 22 highway to be closed.No one was injured during the incident, which started around 8 a.m. and was resolved peacefully shortly after noon, according to the Sheriff's Office.The standoff happened on Woodside Drive, a short residential side street off Route 22 near a cluster of popular businesses, such as the Arctic Circle Drive-in, Churchville Golf and the Churchville Auto Body shop, as well as the State Highway Administration's Churchville Shop, a nearby maintenance facility at Routes 22 and 156. It went on for more than four hours but ended with no one being injured, according to the Sheriff's Office.State Highway Administration trucks block Route 22 near the Arctic Circle east of Churchville on Tuesday morning after unspecified "police activity" was reported by the Harford County Sheriff's Office.Deputies initially responded to a dwelling in the first block of Woodside regarding a report of a domestic incident, according to a statement from Kyle Andersen, a spokesperson for the Sheriff's Office.Deputies tried to contact the man and woman involved but were not successful. The Sheriff's Office Special Response Team arrived and "established a presence at the residence," according to the statement. Route 22 was closed after officers still could not reach either person.State Highway Administration workers used their trucks to block traffic at the Route 22 intersections with Glenville Road and Aldino Road. Around 10 a.m., the Sheriff's Office began advising people via Facebook and Twitter to avoid area because of "police activity."Meanwhile, police gathered along Woodside Drive, which is a dead-end street. The SWAT unit included a sniper who could be seen on the roof of a building along Woodside, across from the house where the standoff happened.The Harford County Department of Emergency Services sent out a countywide robocall to alert residents about the incident at 11:50 a.m.Around noon, the Sheriff's Office tweeted the incident was contained to Woodside Drive and that "there is no threat to the community." The highway was reopened around 12:45 p.m."After several hours, attempts to make contact with the female occupant were successful," Andersen said. "She exited the residence, unharmed."The man came out about 30 minutes later around noon, and police took him into custody, according to the statement.The man was taken to University of Maryland Harford Memorial Hospital in Havre de Grace for an evaluation.No one had been charged as of late Tuesday afternoon. Neither the man nor the woman was named in the Sheriff's Office statement."The Harford County Sheriff's Office would like to thank area residents for their patience throughout the incident, and the Maryland State Police, Maryland State Highway Administration, Harford County Department of Emergency Services and other allied agencies for their assistance," Andersen said.Brandi Hipkins, a manager at Arctic Circle, said later that she could see the rooftop police sniper from the restaurant."There were just cops everywhere," she said. "You could see them getting armored up."Hipkins said she was working alone when the incident started, and she was apprehensive until a police officer came in and told her she could keep the building unlocked."It was a little scary at first, until the cop came in, because I didn't know what was going on," she said. "I wasn't sure if I should lock the doors, hide under the table."Business started picking up at Arctic Circle, Churchville Golf and the neighboring Mane Line Design salon after the highway reopened.Patrons were out and about at the Churchville Golf miniature golf course as things got back to normal.Owner Ken Rizer said he started seeing police activity around 9:30 a.m., and the road was closed around 10:30 a.m. He said a couple of customers were playing at the time, and police allowed them to leave. Parents of children participating in a golf clinic were delayed in picking them up, though, according to Rizer."They handled it professionally," he said of the police.Rizer lamented the road closure and the subsequent loss of business on a day when the heat and humidity that has been affecting Harford County recently had eased."We were looking forward to a nice day of business," he said.Rizer and his wife, Joyce, have owned Churchville Golf since 1988. His wife's family started the business in 1976.He said the community is normally safe, except for the occasional break-in. He has not seen anything like Tuesday's standoff before."[It's] a little close to home," he said.Aegis staff member Matt Button contributed to this report.
