A 20-year-old woman was stabbed in Perryville after a fight last week , the town's police chief said.
An Aberdeen woman was arrested Monday in the incident.
It was at least the second violent incident in the normally quiet town within the past two weeks: a 22-year-old woman reported being raped on June 10.
Perryville Police Chief Charles Wernz said last Friday the stabbing and rape are not related.
The possible upswing in violence, he said, is just in line with the arrival of summer.
"I think it was a long winter and now it's warm out," he said.
In the incident June 19, the woman was treated and released for stab wounds after an argument escalated at about 9:30 p.m. at Perryville Estates, in the 500 block of Broad Street, according to a statement from Wernz.
Police learned that two women had been arguing, which led to a physical fight and ended with the victim being stabbed with a knife, according to the release.
The suspect fled the scene but was later arrested. Martina Darnella Bonner, 19, of the 700 block of Battle Avenue in Aberdeen, is charged with first- and second-degree assault and reckless endangerment, according to online court records. She was released Tuesday on $120,000 bail, according to records.
The victim was taken by Community Fire Department of Perryville ambulance to Harford Memorial Hospital in Havre de Grace, where she was treated for several slash wounds and was released, Wernz said.
On June 10, two area men were charged with rape after a 22-year-old woman reported being assaulted near the Perryville Town Pier, police said.
The woman said she had been physically and sexually assaulted at about 10 p.m. near Rodgers Tavern by two people she knows, according to an earlier Perryville Police Department statement on the incident.
When officers tried to apprehend the suspects, both jumped from the pier into the Susquehanna River, according to statement.
After a brief search, Devin Francis of Port Deposit was found trying to hide under the pier. He was arrested without incident.
The second suspect, Jason Papasarang-Jarvis of Perryville, was apprehended several hours later at his home.
Both were charged with rape, sexual offenses and second-degree assault. Francis and Papasarang-Jarvis are both being held at the Cecil County Detention Center without bail, according to online court records.
The Perryville Police Department was assisted by members of the Cecil County Sheriff's Office, Rising Sun Police Department, the Maryland Transportation Authority Police Department and the Veterans Affairs Fire Department in that incident.
